Hi, everyone! I am new to puppet building and have been trying to make my own for the past couple months. However, I haven't been able to find some cheap, pliable materials, specifically foam. As well as this, I was unsure of how to construct a proper functioning head. I tried to use some foam somewhat resembling the pictures at the bottom, but both were expensive and hard to shape or sew...It would be greatly appreciated if someone could give some advice on foam...hope this was the right place to post and there wasn't already a thread like this! Thanks!
