We live fulltime ( and workamp) in our 39' Fifth Wheel and I have 2 spinning wheels, a Louet S15 and an Ashford Traditional. No problem tucking them in the corners against the wall (but 39'is a big RV!). I also own several hand/drop spindles and last week I found an 16" Ashford Table Loom (which is collapsable and fits under the table) at the local thrift store!
I love to sit outsite and spin and people come up to me all the time to find out what I'm doing, but sofar I've never sold anything yet. My Louet is also a recent thrift store find and it looks I can spin more and faster on that one so I might start selling some! Do you have an etsy store?
