A couple of years ago I switched from annoying disposable pot and dish scrubbers to crocheted acrylic scrubbers (tawashi in Japanese) and made a few simple ones. Since my color-scheme changed here (I made some to match an ugly orange countertop when I was in Athens) I decided it was time to update them and maybe find a cooler pattern, which I did with Japan's
Pierrot Yarns. The website (and pattern) are in Japanese, but the chart is pretty simple to follow. It's the fourth link next to the icon that looks like a page with shapes on it. I love them because they really do work and when they get dirty, just throw them in with any load of laundry. The best yarn to use is cheap acrylic, like Red Heart. I made these for my mom to try!
