All the squares have been sewn and I am indeed very happy with they way they came together:
I've seen other afghans with different choices of colours. But I am glad that I chose to minimize the number of colours used.
The only problem is the afghan came out a bit too short. I would like it to cover a whole person. With the sewing and the inevitable shrinking of the squares after blocking (the yarn is largely acrylic, you know), it is now 53" long. So I decided to add one more row. I would be choosing some squares from the Great American Aran Afghan and the Great North American Afghan that would go well with this one. These 2 are from the latter:
Got to start knitting again. :)
