Last month, in preparation for Pi Day, I participated in a swap on ravelry, where people exchanged Pi(e) themed things. I had purchased these dessert cloths ages ago, one of the six patterns happens to be a slice of pie! Which was perfect.
The only downside to this pattern is that it's knit on 3.25mm needles, which is very tight for dishcloth cotton. Nevertheless, the dishcloths turned out great!
I used Lily Sugar 'n Cream in wine, cream, and brown respectively.
