Here is my free crochet ripple 6 for a wavy ripple dishcloth. I first used this wavy ripple style to crochet a lapghan and just love the look of the stitch pattern.
Here is another dishcloth I crocheted using the wavy ripple pattern. I ran out of the pink twist cotton yarn so I only crocheted 13 rows. I added a white edging around the entire dishcloth by working single crochet stitches around evenly. I worked 2 single crochet stitches in the corners.
This trim edging gives the dishcloth a little different look and may be useful it you are trying to use up scrap pieces of cotton. My crochet pattern may be used to make a wavy ripple dishcloth or washcloth. Mix and match colors to create your own unique crocheted cloths. DC in the next 3 sts, 2 DC in each of the next 2 stitches, DC in each of the next 3 stitches. Row ends with a DC in the last three stitches of the row. DC in each of the next 3 stitches, 2 DC in each of the next 2 stitches, then DC in each of the next 3 stitches. Now work 2DC tog , work another 2DC tog.
