I finished the little cardi after lots of things going wrong
Lots of problems with the yarn getting tangled as I was knitting with two very thin strands of yarn.
I had to do the neck band three times, as first time I hung one front side on the needles with the shoulder seam instead of the neck edge, then I put the fronts on the wrong sides, so the front edges were at the shoulder seams, but third time lucky!
Then I had to do each button band twice due to dropped stitches, but it's done! Just need to sew it up now - and of course I don't have any buttons in the right colour.
