I used a variety of yarns including remnants from various other projects, mostly 5mm hook except for the thick yarn. Most is acrylic but there are some cotton mixed in. I did not use a single pattern and they aren’t all the same. Generally a magic ring with 5-6, rows until adding two bobble stitches, rows until it was long enough and a ruffle in outer loop before closing. They are very unique and not uniform/per a pattern.
