Hi,
I've just finished a string quilt and it is beautiful! I had bought some of the stablizer my local quilt shop sold and after feeling it and its texture (thin) I went to Home Depot and purchased "septic fabric". Its a thin substance they use in ditches and things like that! It was VERY cheap compaired to the quilt shops, I purchased like several feet of it (twenty if I remember correctly) for the cost of about $4.00 or less. I made my quilt and love it!!! However, I made the squares about 8 inches and would have liked making larger squares, you have to be careful it does not fold under you. It certainly made the piecing easy and much cheaper!!!!
