This was the mid-month knit-along, a design by Sharon Hoyt - Garter Striped Chevron dishcloth. It is also available on Ravelry. It will probably be a gift at some point. I added a pattern repeat within each larger repeat to lengthen the dishcloth a bit, mostly because I did on the first repeat, and just kept it even after that. I do like the slightly larger size though.
It is a bit tighter than the previous version, and the colors go with my kitchen too.
