Two projects that are on my list of project to is slippers and an ripple pattern that uses both the afghan and single crochet stitches. I made some slippers that I was happy with using a chunky weight yarn. The slippers with definitely keep your feet toasty warm.
The afghan ripple dishcloth is based on one of my existing Tunisian and Crochet Scarf My technique of using the two stitches makes "tracks" in the pattern. I think the ripple makes the "tracks" a more interesting feature. So hopefully soon I will have a pattern up for the slippers and ripple dishcloth.
