So far, I've purchased:
Simplicity Sew Simple:
I've cut Butterick 5566 in a brown woven fabric and have some nice blue striped shirting fabric for Butterick 5526. I also have some pretty printed fabrics that I intend to use for Butterick 5610, NewLook 6130 and 6150 and McCall's 6565. I bought cotton broadcloth to use for shirts, which patterns I'm not sure.
Update: This is a list of 11 patterns. I'm up to 34 as of February 11th! :)
