I figured this community could use a little content! I freehand crocheted this bag last August using the magic circle to start the bottom, mosaic crochet for the body, double crochet for the flap, and spiral rope crochet for the straps. The button was purchased from a vendor on Etsy.
It was TheMagpiesEyeCo on Etsy. They only sell epoxy buttons, but they have a bunch of different kinds.
