Works on any number of stitches.
Rows 1-4: Knit.
Row 5: (wrong side) *Hold the yarn over your index finger and wrap the yarn around your middle finger, forming a loop around the middle finger. Knit the first stitch, but don't take it off the needle. Slide the new stitch to the left hand needle and knit along with the old stitch, through the backs of both loops. Repeat from * across.
Row 6: Knit each stitch through the back loop.
Repeat these rows for pattern. You can also knit the loop rows closer together to make a denser fabric of loops, or even alternate working the loops on the wrong side and the right side so that you get loops on both sides.
Used in: Loopy Washcloth.
