I am using Foundation Web to make my Triangles with...it is a web type stuff that you sew on and you leave it on for good...you do not take it off at all...you cannot buy this anymore...My church has a Quilting/Sewing room and in that room is a large roll of the Foundation Web that I have been using for my Triangles. I draw the Triangle onto the Foundation Web and than I sew my scraps onto the Foundation Web Triangle Shape and I sew on the lines to get the look that you see on my Triangles. I hope that makes sense..its kinda hard to explain.
