I discovered there's a wrong time to try on a jumper to check that it's fitting nice while your knitting it. I put on my rainbow jumper to check that it was all ok before i knitted the collar. I looked so fat in my jumper I almost cried because I went to so much effort measuring and calulating so it would be a nice fit. I almost frogged it because I felt so horrible in it. I realised later this morning that when I tried it on I was wearing a singlet a shirt and a light jumper. It was too late at night for me to realise that I was wearing 2 jumpers. So leason learned never try on jumper late at night when very tired.
