Mary from The Curious Quilter is doing her annual PS charm swap in October 2016. There are 3 sizes of charms to swap 1.5", 2" and 2.5". This swap is international so be prepared if you decide to participate.
For those who have participated before, Mary has updated her rules a bit so please read. I have participated twice before and have gotten some great charms to go into my stash.
