I am making a sacroiliac belt. It is a firm but moderately stretchy belt that goes around the hips for some kinds of pelvic instability.
I couldn't find the appropriate material, so I got three inch heavy elastic, and I am sewing several 48 inch strips of it together, back to back.
What is the best way to fasten the strips of elastic together so that they remain elastic? I am not using a sewing machine as I do not own one. Should I use a zig zag stitching pattern, or should I just tie knots on each side every so often?
Thanks for your help.
Yours, Dora Smith
