I just finished crocheting the Calico Flowers Scarf. I followed this free pattern from Yarnspirations. I used a 6mm hook and rainbow cotton yarn from Shopee.
The pattern is intermediate-level, but I think it can be doable even for advanced crocheters. Just be sure to count stitches and ensure that the gauge is followed.
I hope that this inspires you to make something during this pandemic. Creating beautiful things is uplifting and fulfilling. Do give it a try!
