So, who uses an abacus nowadays anyway?
I was set to the task of coming up with a knitter’s abacus. One of the gals at my LYS had purchased one but it snagged her knitting. She wanted one with my flush-cut jump rings. Apparently they do not snag, and folks love them.
I chose to do my first prototype in shrink film. I love playing with that stuff, and it turned out very well. I added a definite geek factor to them by using the same color code used in transistors. I will be following with a bead version, and increasing the number of links to 10, per requests by those who have seen them.
