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!!
