When I went outside to take pictures of it, I found we still had a couple of patches of forget-me-not in our garden. So here is the hanky pictured with the real thing!
I used Lizbeth size 40 so it grew quite quickly. I crocheted one row with white thread around the hanky first, then used the pink thread and crochet to attach the lace to the first white row.
Simple, but pretty I think.
