This is a pretty common pattern that I don't think has a real "source." So here it is:
Cotton like Sugar n' Cream (or cotton chenille for an elegant facecloth)
CO 4 stitches
Row 1: knit
Row 2: k2, YO, knit to end
Repeat row 2 until washcloth is the desired size (I like 40 for dishcloths and 45 or so for facecloths.)
Dec. row 1: k1, k2tog, YO, k2tog, knit to end
Repeat dec. row 1 until you only have 4 stitche left, knit last row, and bind off.
Super simple and very easy to memorize. These are great for those knit nights where you end up talking instead of counting!!!
Remember to take it easy everyone. Knitting is supposed to be fun!
