Here's my first scrubbie! I cast on 17 (not intentionally) and then knit about 12 ridges. It's almost as long and wider than my hand so I thought it was big enough. My size 11 US needle is off hiding somewhere so I used a 10.5 US and it seems fine. This one is aqua netting and white yarn.
It wasn't hard, but it did take me a couple hours (with a break or two) because I kept having to wrap the netting around the yarn. Did you do that, Dollyce or do you just hold them together and knit? I actually can't wait to do dishes to try it out!
