I've been looking for some crochet lace patterns lately. I want to make one of those shirts that has the lace in the back, but I didn't want to just buy a lace fabric. I want to crochet it myself. I found this pattern on Ravelry. It is for a triangle shawl, but I adjusted the pattern so I would only get four "pine cones" in a diamond shape. I'm thinking a lacy butterfly applique would work too. I'll keep you posted on the shirt as I get to it.
