Lima by Lisa Richardson is a super fun pattern with gorgeous results! The pattern for either the scarf or cowl calls for 1 skein of each of 2 colors of Island Blend, a luscious wool/alpaca/silk blend.
Both are knit using size US 6 needles (at least 40in circular for scarf, no more than 32in circular for cowl)
