Review on 🧶 Loom Potholder Loops Set - BENBO 192 Pieces Multicolor Craft Loops, 7 Inches Potholder Cotton Loops with Crochet Hook - DIY Crafts Supplies for Weaving by Morgan Gilmore

Product info says these are cotton loops. It's not cotton, or at least not very high cotton content. They stretch to fit the loom but will bounce back when taken off, making them almost impossible to knit in. And if you succeed, the resulting tack will be very slight See photo: The right one is made from whatever cotton loops came with the loom. On the one on the left is the one made from these loops.
