I decided to revisit paper embroidery again for the series, and went with bullion knots in blue thread for Day 21. I did not plan out what I was going to do beforehand so the design I came up with is a bit of an improvised mess, but I like it.
Embroidering paper is unforgiving. Once you punch a hole through the surface to make a stitch, you’re committed, even if you misjudge the position of a stitch.
