I love things that come in mini sized and clothes pins are no exception. I love Japanese Washi Masking Tape in any size. Marry the two and I’m a happy camper.
I used two different tapes on each clothes pin, one on each side.
I did a version of this craft (if you can call it that) a while back with grown-up full size clothes pins. The beauty of using these little guys is you can apply the tape directly to the clothes pins without using white sticker paper as a base.
