- travisporter 7y agoReally grateful for this resource, but the instructions are not exactly clear. Do you take the t-shirt and make it a single layer of cloth or somehow cut the shape into "1 outer layer (≈37 cm × 72 cm) rolled and cut as in panel B with 8 inner layers (<18 cm2) placed inside (against the face)." How do the inner layers stay put?
- dwighttk 7y agolooks like the 8 layers are sewn to the single layer. Or possibly the innermost is sewn to the outermost and the other 7 layers are put in the resulting pocket.
