I knitted my first rug! I didn't use a pattern, but here's how I did it. I used size US 9 needles with 2 strands of worsted and 1 strand of something finer to knit the squares in garter stitch. Each one is 20 stitches by 19 rows. I sewed them together, then I knitted the border onto the edge by casting on 7 and then picking up stitches at the end of every other row.
