I just discovered an amazing crochet technique: Bavarian crochet !
If you don’t know what it’s about, just have a look at this tutorial on Youtube: Bavarian Crochet
I had immediate inspiration for a pattern for mitts with this particular stitch. Another great idea to get rid of leftovers indeed ! Here are the pictures.
Update: the crochet pattern related to the Blue version is for sale here ! I hope you enjoy.
