How many layers of hemp/cotton did you use? I was thinking I'd just use my microfiber insert as a pattern and sew the layers together around the edges?
How many inserts do you think a yard would make? Also what type of thread would I need to use? Would a poly/cotton work?
A yard of fabric is about 54 wide, and then 36 long. It will shrink maybe 10 percent. So figure 50x30 to be safe. You should get 4 cuts x 10. So depending on the number of layers per insert you use will decide how many you get from a yard. I wouldn't go more than 3 layers, then it gets hard to dry.
