2011 #1: I've been a busy little beaver, knitting up three different kinds of squares. All very simple. This design started with a gift of yarn; just one ball. So once it gained a life of it's own, I had to scramble to find other yarns to go with it into a project. It is all acrylic because, well, that's what the gift was, and it is going to be a mat or blanket for a baby. It should be as easy to care for as possible. The mat.... not the baby..... they are never "easy". The yarn I received was the variegated one in the bottom left. Aqua to blue. Very soft. Nice for a baby. Then I bought the plain darker aqua to match. But the gauge is different so I made simple garter stitch, to preserve the thickness across the mat. Finally, I was at a yarn shop that carried the same soft acrylic but I couldn't get the exact colour, and so we have a solid lighter aqua. Yes, there isn't an even number of variegated rectangles, but I don't mind, and I don't think ...
