I'm starting another reknitted sweater, and it's already become "hold my breath and hope I have enough yarn" time.
I wish I knew a trick for being able to figure out if the amount of yarn I have is enough to do what I want, cause I'm never sure and, frankly, never know until I'm most of the way done that I'm going to run out. I have this sinking feeling that if I have enough it's going to be just barely and I'm probably going to have to rip out a bunch and make some design changes before all is said and done. Ack!
I guess I'll just have to knit with my fingers crossed from now on. :)
