Didn't get as much done as I'd hoped but here's my fly stitch "doodles":
I started a new combination but didn't get it finished.
Here's a little flower using my new fly stitch skills.
A few of these stitch combinations are found in this book, The Stitches of Creative Embroidery. It's not the sexiest book around as there are no fancy color photos but it's been useful to me. It's out of print, but Amazon has used copies. Check my blog in a little while for some photos of a very basic fly stitch on my CQJP block.
