Here is my trellis stitch center(I know it needs work!) and my detached buttonhole petals. You can see the left petal is a little bit better that the right one. Its not great, but I am determined to master it! I also had a little trouble with the back stitch base-the pattern is not the clearest-it is from am old Fine Lines magazine. But I will continue and see how it comes out. It's really fun!
