Ok, I ordered the spools but COULDN'T WAIT!
So I went to Joann's and got 5 yards of white nylon mesh and cut it into strips. I made one scrubbie CO 15 (ran out of yarn on my Long Tail) knit for 22 rows (I thought that would be 11 ridges but it ended up being 12) and cast off. I feel like it's too big for me so next one I'll do 10 stitches and 18 rows and see how that works.
Even though it's too big for me, it works like a charm and made cleaning my fridge this morning VERY easy!
