I used a darker, reddish thread to make the border. I should have used a tighter zig-zag stitch, but I was experimenting with a wider one (see the spaces between stitches?). Turns out you have to do this very slowly to make it look good. Too bad I was impatient and messed mine up.
- Try a permanent stabilizer (I just used the kind you pin on and it bunched up a bit).
- Go slower.
- Use the smallest zigzag stitch available if you want the "satin" look.
Oh, well. I'll post when I sew something else.
