I also saw and vendor at the market who used strips, I think she was using 2" to crochet fabric rugs. She had a huge crochet hook and was doing a double crochet stitch. I think for an oval rug she started with a chain and then just started double crocheting but was going around her chain rather than back and forth like you normally would, the effect was really unique and when she got the end of her strip she would fasten on another one and keep going
