I had seen dishcloths and potholders like these before, there are quite a few variations of this general pattern. Some are sc, some dc, the vintage potholders are often double thick (I will be making some of those soon!). I think the general pattern has been around for some time, it is simple, easy to remember and practical. The ones by Apple Blossom Dreams (it was a free pattern when I made these, now it is only available for purchase) really caught my eye, they were so pretty and colorful that I just had to make some of my own.
