Yes, you can do this!!! I agree with all the others -- work in 15-30 min. increments and you'll be able to see progress immediately!!
Do you have a plan for how you want these rooms to look when finished? That helps when trying to sort and organize. Buy some pretty boxes for patterns (JoAnns always has some beautiful ones!) and some "roll around" carts for notions. Put all the same kind of stuff in one area (fabric here, thread there, etc.) and before you know it -- you're on your way to get your beautiful treadle!! :D :thumbup:
