Pitch foam sheet problem Posted by azag93 on Jun 07, 2016
Hi,

I was building a puppet and I had no problem with make pattern, trace and cut edge perfectly with x-acto knife.

I use either hot glue or cement to put foam together into shape and what happen was, is as I put together and even light pitch
both side and it turn out the seam is not flat curves. It turn out not smooth shape edge. What do I do wrong?

It looks to me like your curve is wrong on your pattern.  I think you need to soften the curve some.  Try cutting the foam you have already put together down some on the part that is curve is to much and then glue back together. When you get what you like then transfer those changes to your pattern.

Thank Shawn. I give it a try later and let you guys know how I goes!

You might have pinched the foam together too hard when you glued it. I do that a lot. You don't need to put much pressure onto the glue for it to stick to the foam. If you fleece it, get thicker fleece so you won't notice it as much.

Since the outside of the foam seam is the most important I angle/bend the foam to make the outside edges touch first, gently and slowly line outside edge up, then let it touch the rest of the foam seam width.  If you pinch the seam from the topside it can make it stick out instead of being smooth.  Better press the whole foam straight from both sides holding a little further back on the foam from the seam.  That is hard to explain, wish I knew how to video that.  I learned that the contact cement holds better than I expected with less pressure. Your seam looks better than some I have had. A tight skin over that might smooth it out some more too. I agree with Shawn, don't be afraid to try again until you are happy with it. Perfection does not always come the first time.
