Here’s another Christmas motif . . . the time-honored bell. I think it looks best as an outline, but the solid version also looked pretty good to me. The double outline did NOT look good, so I don’t recommend trying it.
This works as an O or a 0 (zero).
This letter is a little funky. I originally designed the last set of U3 on R2 as optional, but after weaving both, I prefer the serif-like addition.
The two optional sets of U3 (last stitches of R14 and R15)—I prefer not to include these, but you might want to try both and see which you prefer.
