(Sorry - I'd make it bigger but for some reason the program is squashing it so it's unreadable no matter how many times I load it. So click on the thumbnail to see the stitches)

I really like this one --- if I didn't hate stitching with metallics, I could see the chain stitch in gold over a ribbon or even a fuzzy yarn. But I do hate stitching with metallics so I stopped with perle cotton!
