Knitting Squares

I have mentioned that I have knitted rectangles for years; mostly scarves and prayer shawls. One would not think that learning to knit squares would be big news! But it's actually been fun. Jill found this pattern for dishcloths and I have learned to knit squares. It's unique because the pattern instructs that you start at one corner and increase each row then start decreasing down to the far corner. I know. . . must be a simple woman to feel a bit of a challenge at knitting a square, but it's a good way to use some cotton yarn. Anybody actually use knitted dishcloths?
