I wear flipflops a lot, and I wanted a simple pair of black tabi socks, but I hate knitting with solid black yarn.
Solution: knit in just about any boring colourway, then overdye with Rit! I found an excellent buy on yarn...2 skeins on sale for just $5, a hard-to-beat and impossible-for-me-to-pass up deal.
Serenity Sock Yarn. Needles: 2.25mm
I love new socks, even simple basic black ones!
