This video demonstrates how to sew a blind hem stitch to make Roman shades. This stitch is very easy to do. You need a sewing machine that has a blind hem stitch already programmed in it and a blind hem foot. The video shows two different kinds of blind hem foot for two different sewing machines. The one for Viking machines is used here. Fold and pin a one inch hem on your panel, making sure that the pins are pointing off the edge of the panel. Lay your panel on the machine with the hem side up. Fold the end of the panel under so that only a quarter of an inch is still showing. Insert the edge under the sewing machine foot with the mid line of the foot lined up against the folded edge of the material. Sew your material so that the needle just catches the folded edge as it goes along. When you are finished you will see a full line of stitches on the back, but only some very small marks on the front of the material. So long as your thread is the same color as the blind, you will not see any trace of the stitching once the blind is hung up on your window. That's it!
