Foam Terrestrials

[Flysmallie]

If the color of thread that is on one of bobbins is even close to what I'm thinking then it's the one I use. Mostly 6/0 but will use bigger thread for some bigger flies. GSP for deer hair. Any thread will cut any foam. It's all about learning how far you can go. I haven't cut foam with thread in a very long time. Remember, you don't need to cinch it down on the first wrap.
