No, I can't.
Despite my best intentions (and public declarations at home in the living room -
"I will not buy yarn! I don't need to buy any yarn right now!"), I came home from Walmart with four skeins to finish off the pineapple pillowghan. Two each of Red Heart Delft Blue and Soft White. I'm pretty sure it will be enough, and I'll have an extra skein of the Light Blue to make up any difference and join the squares together. If not, I guess I know where I can get more. Ha!
