I now have my frogged wool ready to use so have been able to complete some of the hexagons I had started.
The jumper was frogged into balls and I was going to wash them as balls until I read a bit about frogging on the internet. Apparently they suggest that you should wash the frogged wool as skeins rather than balls.
I then unwound a few balls into skeins and gave that a go.
This is how the skeins looked after being washed. I wasn’t convinced that the result was any better than leaving the wool in balls to do the wash so I only did what you see here, the rest I left in balls.
I am happy with the result.
