Took me forever, but I've finally finished up frogging the scrap blanket! I'm left with what I can only describe as a bowling ball out of yarn!
It measures 71cm (28") in the round and weights in about 1,3kg (2,86 pounds). That equals to 26 50gr skeins or "normal" skeins.
Now I just need to decide on a stitch and start all over again!
