So, eventually, I settled on a mitered square. I read a few different tutorials, knit up a couple of samples and, combining techniques, I settled on a method I liked best. I decided to knit all the squares first, without joining them as I went, for a couple of reasons. Some people can visualize a finished project very well and can plan ahead or they are happy with random but I knew that I would want to shuffle the colors around in a grid once I had completed all of the blocks. I also wanted small, small knitting in my hands, not a growing body of work. So I opted for the strategy of knitting all the blocks, then crocheting them together.
I did think about making my blocks into an afghan but after 25 or 30, a pillow seemed like a better option. My friend, Barbara, just got a beautiful new rug in her pretty new house and the colors of the rug and the pillow were meant to be together.
I think it might need a bit more of an edge so we'll give it some time and see what Barbara wants.
