Recently at a fabric exchange that my wife and I participated in at a local quilt shop, the fabric to be exchanged were to be 10 inch Amish colors. When we purchased out fabric, it was 100 % cotton (Kona). I know from the feel of some several squares that some one purchased poly-cottons or broad cloth. I guess I'm questioning using this in a quilt. What are the pros and cons of mixing cottons and poly-cottons?

Also someone (probably 20 years ago) gave me a paper box full of plain colored fabric, I dug them out and know they are poly-cottons and cottons. What is the test to determine 100 % cotton? Can this be used for charity quilts? I know if I want it to be a keepsake quilt, I'd use 100% cotton.

I've got the half-square triangles sewed, pressed and sized for an Amish Star quilt - background color is Kona black. Need to keep going on it.

Take care - happy sewing. Robert, in northern Iowa.
