This was my first afghan I had ever made. I made it with the intent as a gift for a friend and he absolutely loved it in the end. It was my first attempt at both an afghan and the ripple pattern. I used Red Heart Super Saver yarn (this is how I fell in love with Red Heart yarn for afghans), and a size K crochet hook. The entire pattern is double crochet, with 4 rows of each color, repeated 8 times. Total = 128 rows and approximately 32,000 stitches. I was proud enough of my afghan to attempt to calculate that, ha! It measures 68.5" x 90" so it is quite large and even fits on a king sized bed. I added tassles on each "peak" on both ends of the afghan, containing one strand of each color, and added a black edging around the afghan. The pattern is homemade, but I found a very helpful formula to generate the correct number of stitches for my foundation chain. I found it at pumamouse.com labeled as the ripple formula.
Extremely useful for all ripple patterns!
