One of the interesting things about making things for myself is that it requires me to consider exactly what I like and want. When I buy a sports sock from a shop, the leg is the length they made it, and I'd never thought much about details like that, before I started making my own. Since I started making my own, I have spent a great deal of time considering excactly what my requirements are, and developing the perfect solutions, not just what i happen to be able to buy. This is true, not just for socks, but for the width of Leon's jumpers, the length of my sleeves, basically everything that I make.
The last bathmatt I made, in July 2011, I simply crocheted until I ran out of yarn. I figured that, on a cold marble bathroom floor, bigger is better. When I was knitting my current one, I wanted it big enough that we can both stand on it, but not so big that it takes u- the whole floor. So, having thought about it, I stopped my ten stitch bathmatt when it was just a bit smaller than the old one, and it sits [perfectly in front of the sink.
I guess it won't surprise any of you that what I am saying is that, when you make it yourself you can (try at least) to make things exactly the way you want them.
