While I was searching on Etsy.com, I found these threads. They were from someones mother and aunt, so they're older, are mostly size 70, and they are different colors than I've seen in the stores. Notice the little holder in the left of the pic. The thread inside was mine, but just wanted to see if it would fit. You probably know that it's to hold the thread while in use so it won't tangle or get dirty. I had never seen one made specifically for that purpose. The ones in the store are primarily for knitting thread, big, bulky, and rather expensive! I love this tiny one!
