I was resigned to not finishing round 12 before round 13 came out, because I was busy sewing shirts. But yesterday, just as I was about to start the buttonholes on shirt 7, pfft, the power went off. Tatting, of course, doesn't require electricity, so I got on with round 12. By the time the power came on again, five hours later, I'd lost my sewing oomph and was intent on finishing round 12! So it's done in time. Now I must get on with shirt 8.
