Two days before going to the MD Sheep and Wool Festival is not the right time to go digging through your stash.
You might find lots of yarn that you forgot about (including some that you bought last year at MDSW but haven't used yet.) This might make you feel somewhat guilty about spending several hours buying new yarn.
Not that it's going to stop me. My constraints are already set in place.
Time and money.
Time: Going to DS#1's afternoon baseball game will shorten the day, and
Money: Need I explain this?
However, on the plus side: I've been there before and know the lay of the land. I'm thinking that the constraints will both end simultaneously, thus preventing DS from a LOOOONG walk home.
Off to sleep and dream of yarn.....
