Oops

Oops it's another knitting one, sorry.
My main project is Debbie Abraham's mystery blanket which is knitted a few squares each month, January to October. The colours are lovely and there are beads, buttons and glinty gold bits. I usually knit in the evenings by artificial light - those yellowy slo-mo ones. This morning, after my four week baby knitting hiatus, I get the last strip I made out in the natural light and argh - the very first square has a wrong colour in it. All ripped it now and in ten years it'll all be forgotten.
