My humble experience was ripping sheets into strips about 2”. I recall pressing in half then turned raw edges in to the fold so no raw edge showed. Does not have to be perfect. I’m terrible at crochet but I used a huge size hook & crocheted into a round rug. I recall increasing a stitch on each of the 4 “corners” every round or maybe it was every other round. It actually turned out nice & I still use it in a bathroom. That was 15-20 years ago. It washes up great but I don’t machine dry.
