I decided to invest in some tags after someone contacted me about a month ago, overjoyed he'd finally found my socks again. Apparently, he'd lost my business card, couldn't remember my name, and had been searching and searching (good thing I moved in to internet sales!) and finally found me. He said that the screenprinting I used to have done on the bottom had worn off, which made me start considering my tags.
I did some shopping and was really glad to find someone that could make small batches without me having to invest in plates, use stock fonts, etc. So now I have tags! They're located on the outside of the cuff on the left foot of my tabi, only. They're sewn on and and easily and safely be removed, but I'm excited about them. (Excuse the scraps of thread that i didn't remove before I took the picture, please! :))
