Until this minor setback I was making good progress with the door-snake making. I've filled the first inner snake with sand and stitched the end together, and made a test piece from scrap to experiment with the techniques I'm going to use to make the outer skins.
That is not one of the outer fabrics I'll be using. When I make the first real outer skin I'm going to try to round the ends more, and maybe stitch the tongue into the opposite end to the end that opens when you want to remove the inner for washing.
