Sometimes I sew very heavy fabrics on an industrial sewing machine (straight stitch with walking foot). This fabric is a special fabric that is for Grayflare Inc. It's a laser barrier curtains, window covers, etc.

Since the fabric is a little hard to grip, I do use a pair of garden gloves to hold on to the fabric. In this photo, I am sewing on a hook side of the hook-and-eye tape.
I often need to sew on a bias tape to cover up the raw edges.
If you need a laser barrier, please visit the website of Grayflare Inc. They also have blackout curtains, too. It really makes a room dark!
