ok today we're going to cut foam
you know foam is kind of like a bread
the bread that you should not
but it's kind of like bread it's bubbly
when they make foam they put it into a
great big bread pan if you will and they
cook it and it bubbles up and the great
big piece that comes out before they
slice it into pieces they actually call
a bun so you see there's a bread analogy
so if you think about cutting bread what
was you use to cut bread a bread knife
this is like a bagel knife a cake knife
any kind of serrated edge type of a
knife actually the longer the blade the
more easier it is to work with but some
type of bread knife a lot of times you
can get these in oh you know Target or
whatever for five bucks or something so
here we are we have a piece of foam
right here for example you can see this
one has been cut in a slightly angled or
slightly curved direction and of course
we'll talk about this later but you can
glue foam together
this one's been glued so how do you cut
foam well what you need is a sharpie
marker and you want to mark off the line
that you want to cut I've marked off a
straight line here and then I'm going to
use my bread knife very simply to cut
this now what you want to do is you want
to score the foam rather than saw the
foam so to score the foam you're just
going to go straight across and don't
press too hard press lighter it's better
to do a number of light strokes and just
one or two heavy strokes you'll get a
smoother cut so depending on how thick
the foam is you can cut right through it
now key thing is you want to make sure
that your knife is at a 90 degree angle
or else you're going to have a kind of
jab or walking type of piece of foam so
make sure you're keeping it out and even
angle nice and light strokes and you can
see that it cuts a very smooth a
reasonably smooth line now remember foam
is going to be under pressure in most
cases with the fabric and also usually
it will put a little bit of batting over
top of it anyways only
you'll get a curved line now if it's a
gentle curve you can still use the same
method that I just showed you a minute
ago but if it's a more radical curve
such as this one that I've shown you
here you may have to put your knife at
aside now it's a little more tedious you
got to pay closer attention but you can
still do it just do little nibbles at a
time making absolutely sure that your
knife is at a 90 degree angle don't try
to cut too much at a time just little
nibbles and you'll see even on a
somewhat radical curve you can get a
pretty good line there you go it's a
little bit you know not totally smooth
but it's close enough
that'll work for what you need to do so
that's how you cut foam with a bread
knife
