Once upon a time, in an island far far away, I used to crochet and knit copper wire and sell them as strange-looking jewelry. Moving to where I am now, I didn't know where to get the right supplies, so I ended up crocheting and knitting regular yarn, and eventually sewing linen. They made my fingers bleed occasionally, but I still miss copper.
P.S. That circle in the middle of the last row is a wristlet, still unlined.
