No, I thought not. But I am learning to how to block more than trying to improve artificial yarn - I find the measuring and getting it square very hard - left to myself I produce parallelograms. luckily Andy was around this morning and he helped me again - he might have to go through it ten times, but I'll get it eventually.
It's come out exactly the right size, which is a bit of a mystery because when I did my tension square I got 1 stitch and 1 row too many, but decided I didn't care. In the past, my Alefs have turned out too large, so I'm obviously doing something wrong.
