Pattern:
Row 1: CH6, SC in the 2nd ch from the hook, SC in remaining 4sts
Row 2: Pull the loop on your hook to make it big, then insert your stick into the loop, *insert your hook into the next stitch and pull up a loop, then put that loop onto the stitck, repeat from * with remaining 3sts. You should have 5 loops on your stick and no loops on your hook.
Row 3: Carefully insert your hook into the 5 loops on your stick, YO and pull through the 5 loops, CH1, holding the loops in place, SC5 in through the 5 loops
Repeat rows 2 and 3 until you reach your desired length and bind off. Keep in mind that your yarn will probably stretch at least a little bit, so ending 1 or 2 stitches early wouldn't be the worst idea. Sew on button and weave in loose ends.
