Use a gauge of one wave (top of one wave to top of next wave should be about 4-1/2 inch) and 5 rows should be about 4 inch) over pattern to crochet a throw that measures approximately 42 inch wide x 67 inch long. Be sure to check your gauge. If it takes you less stitches to match the gauge, try using a smaller size needle or hook; if it takes you more stitches, try a larger size needle or hook.
