Quilting Tips & Techniques 257 - How to cut a 60 degree diamond shape.



Sharing buttons:

hi today I thought I'd show you how we

can cut some 60-degree diamonds now that

might sound a little scary but they just

look like this so and diamonds are a

girl's best friends so they say so the

60-degree bit comes in on this internal

angle here this is a 60-degree angle and

I don't want to confuse you all with

math so I'm definitely not a mass guru

however I do know is that with a

four-sided shape all the internal angles

need to add up to 360 degrees so on a 60

degree diamond this is 60 degrees this

is 60 degrees so added together those

are 120 degrees and these opposite signs

these ones each are 120 degrees they're

actually double this so that means 120

plus 120 is 240 plus another 120 and

we've got to 360 so we know that a shape

is going to work and as I said all four

sided shapes add up one way or another

so we want them to be fairly even we

want them to work together for patchwork

so I just wanted to show you how you can

cut some of these shapes so all you need

to have you can buy templates and rulers

that are particularly for 60 degree

angles however many of us have rulers

that have markings on that perhaps we

hadn't thought about using so I have my

own rulers here and these have 60 degree

lines 45 30-degree and this is a roller

that many of you be familiar with the

Omni grid rulers they have a lot of

angle marks and things on them as well

so I'm just going to show you with the

Omni grid ruler because it's probably

easier for you to see even their smaller

ruler that I have here has those same

markings on so you'll find that very

likely you've already got all the tools

you need to cut 60 degrees diamonds and

you'd probably didn't even know that so

I'm just going to use my my cutting

board to help me a little bit here

because cutting boards also have a lot

of markings on them so very often they

have these diagonal lines that come in

at 45 degrees from a straight line there

but this one also had ins to have some

markings here with different angles so

that's also going to help us line things

so I'll show you me you might use those

to your advantage because most of us

have a lot of these tools as I said and

we don't necessarily realize that we

even have them half the time so I've got

myself a strip here so I'm going to cut

some some diamonds the same size as I've

got up here on my wall and I've started

with a four and a half inch wide strip

of fabric so I'm just going to lay that

on my border and I like to lay things so

that they run it along one of the long

lines on the board so that I know

everything is sitting straight and then

I'm going to take the ruler here and I'm

going to take this line here this one

here says that it's 60 degrees it's

intersecting with one going the other

way but this angle is a 60 degree angle

so I'm going to use that angle now I'm

going to turn that round here and that

60 degree line I'm going to line up on

the bottom edge of my strip here

and I'm just going to bring it in there

like that

and I'm just going to lay that right

along that edge so that yellow line

follows the edge of this yellowy colored

fabric and I'm just going to cut that

angle up there so we know everything

sitting straight and square because

we've squared it up on a board with

where their ruler up with the 60-degree

and now I need to cut another line

opposite that which will be parallel to

that that means it's running exactly in

the same direction and as equal distance

apart and I'm going to turn this around

and I'm going to come back over here

onto the markings on my board and again

I'm going to line my fabric up so I've

got this line here that tells me that

it's a at 60 degrees from up here so

that's the line I want to follow and if

you lay your fabric along one of these

lines on the board you'll see that that

actually lines up with that line so so

far we're doing pretty well so now what

I need to do because I know that my

strip was four and a half inches wide I

need to cut these other two lines so

that they're also four and a half inches

wide so I don't need the angle now

except to keep things straight I just

need to know where four and a half

inches sits on my ruler so I'm going to

line up the four and a half inch line

which is halfway between four and five

right on the edge of that fabric that I

previously cut so that sits there and

because I've laid it on that angled line

I can line that line up a little bit

further than just the fabric to make

sure everything is sitting nice and

straight now that line doesn't go

forever but it does go a bit further

than the fabric so I'm lining that up

there it's sitting nice and straight and

now I can cut the opposite side there

and what I've ended up with really quite

simply it's a 60 degree angled diamond

and I think that that's kind of fun to

be able to do that and we can have a

little bit of a play with how we set

things together and I'll have a little

bit more of a play in a minute

I'm just going to cut a couple more

though I want to cut one out of the dark

fabric because I want to be able to show

you what you might do with them now I've

already got a line on here because I'd

already cut that one from this stripper

before and I'm just going to lay that

now I've cut it round the other way

obviously line this up here with my line

line up my strip and I'm going to come

whoops round the other way sorry

line it up with my strip line it up with

my the line on my board so that

everything's sitting nicely there and

again come in four and a half inches

onto that cottage and I'm just going to

cut that line there so there's another

one for us that's looking pretty good so

far

probably not exciting in that array and

now what I wanted to do was just I have

another little um just to show you

another little thing you might want to

be cutting a lot of these in which case

you might want to lay more than one

fabric together and I would normally

have cut those together so I'm just

going to trim that edge again with my

sixty degree line running along the

bottom here I've lined them up with that

but you can lay two together so usually

when I'm putting two strips together to

cut something particularly a a more

specific shape like this I would on one

strip out flat on my ironing board and

then I would lay the next strip on top

and also I net right on top

so that everything sitting together and

it just helps them sit together quite

nicely so I'm just going to trim that

little edge off to make sure that those

edges are the same I've got my 60 degree

line of running along the bottom edge of

my fabric trim that little bit turn that

around line it up with my angled line

here on my board and also that edge

along one of the lines on the board and

then come along my four and a half

inches and cut that there so you can do

this with several different sized strips

and I might just quickly show you the

exactly the same process on a couple of

other sizes I'll show you those in a

minute

so I've got a wider one here a six and a

half inch strip so that's sometimes a

little bit more of a challenge when

things are a little bit wider but I

think we can do it so same thing I'm

lining that up with my lines on my board

I'm going to line my 60 degree line up

there and just make sure that your ruler

is long enough some of us work with

short rulers sometimes

cutters line up there because you might

have different size strips you might be

making a different size project the

cutting is the same process because

we're just cutting to whatever the width

of our strip is basically so I'm going

to line that up again with that 60

degree line on my board line up my

fabric straight edge with the lines on

the board and I'm just going to now come

oops my rulers not wide enough now what

am I going to do get a wider room so

some rulers are wider if you're going to

work with six and a half inch strips and

this is why I've done this muck this

ruler is six and a half inches wide

sometimes we're a little bit short so

sometimes you've got a different sized

ruler for something or you could have

just measured along and come up with six

and a half inches but I thought I'd just

show you that this can happen so we

might need to position that so we can't

cover every part of the line there but I

know that this is six and a half inches

wide my strip is six and a half inches

wide so very often once we've done that

first cut which you don't need the wider

role or fourth there's a way around

doing the next cut you might have a much

longer ruler in which case that's fine

too you can work out different things so

that's just a much larger diamond same

sort of dimensions that are staying with

the 60-degree angle here but a different

size and then these days a lot of us

like to work with two and a half inch

strips I just thought I'd show it's the

same process but just to make sure that

you you can use up all those nice bits

and pieces of fabrics that you've got

sitting in your cupboards so I've lined

up my two-and-a-half so we have a lot of

us have two and a half inch strips and

you can cut them with the two and a half

inch strips just the same they're just

smaller so I've got my 60 degree line

along this straight edge of the fabric

cutting that off there turning it around

lining it up and this time because it's

a two and a half inch strip I'm just

coming in two and a half inches so then

I've just got a smaller diamond so how

fun is that we can just about do

anything and then there are lots of

things you can do with these diamonds

but just one quick little idea just

might be working with two colors you

could work with many colors but I've

just got two today and you might make a

star type shape so it'll be a

six-pointed star of course this size

diamond because six 60s make 360 so even

though we're not actually mathematicians

we use quite a lot of maths in quilting

and don't be frightened by it it all

kind of works out there is quite a lot

of maths in course so that's that's just

an example of something you might make

using a six-pointed sorry a 60-degree

diamond there's other things and this is

just one of several videos that I'm

doing we're going to be showing

some different ways and different ways

of cutting and or not so much different

ways of cutting about different sizes

different things that you can do with

some of these diamonds so come back and

have a look for the next video thank you

you
