Not Ranked. Helpful AND tactful post? : 0 Re: Making a "sleeping bag" cozy. (part 1) | | When I make the cuddlecups and tunnels with the foam, I try not to sew through it at all. Rather, I cut the foam a bit smaller all around than the fabric, and just sew fabric to fabric. If you need to sew through it (like in this project), I put the foam on the bottom, the fabric on top, and flatten the foam with my hands nearest the pressure foot, so it sews more easily. |
