Sure, it works up fast if you work consistently on it! I on, the other hand, have a bottle of Asahi I've been making since October and it's wildly overdue for my friend's birthday I've just been too lazy to embroider and seam it, that's all.
I know what you mean about all that extra yarn. When I submitted my yarn requests, they advised asking for a little bit more than I thought I'd need just in case. I wound up with at least 2 skeins of each color, when most of them barely use one. I've been making things out of leftover Wool-Ease for months! (I know the pattern calls for Vanna's Choice on the beer bottle, but I actually used Wool-Ease for the whole thing, the Vanna stuff wasn't out yet).
