I'm nearly done a set of 3 frog dishcloths for my niece. Yep, I'm knitting three at a time, each in a different colour. And, believe it or not, these will be part of her Christmas 2015 gift, so I'm really starting early this year!
The thing is, I'd probably be done by now if I didn't make a mistake within the first third of the dishcloth - and the problem with knitting two or more of something at once, is that you're likely to make the mistake on each item. So, I've had to rip back to undo my mistake on all of them, and reknit everything.
That's right, I've had to (partially) frog my froggy dishcloths. Ha.
