Jan, there are spinning wheel plans available
Wheel Plans. Some of these look quite compact so you could put them in the closet when you were not using it.
For the roving, check at your LYS. I didn't even know mine had it because it was shoved in a corner. The lady showed me a shelf in their back room with bags and bags of roving in the yummiest colors! Of course, I had to buy several different colors! Now I just have to practice, practice, practice so that I can actually spin it into something I can use. Good luck!!
