I have my patterns picked....I am going to do the soft waves on page 19 of Jan Eaton's book and storm clouds on page 47. How do I know how much yarn I need? I want to go and get this today, so any help would be greatly appreciated. On the soft waves It just says 12+3 and on storm clouds it says 17+3. Both of these will be adult size blankets.
THanks for any help!
