I liked the smaller size, so I made another piece with the distance of the loom at 1 cm. I had seen some rickrack hairpin lace online, but I didn't know where. So I had to try . . . and try again . . . and again! It took some time, but I'm happy with the result. The size of the rickrack is 2 cm (3/4 inch).
If you want to know more about hairpin lace, just read my first post about it where I wrote about a few helpful tutorials.
