You need a craft shed/garage/workshop/den whatever your OH calls his workshop/shed space.
Of course it would have to be well insulated and heated so the equipment didn't suffer damp.
I think it is a problem with any hobby, one thing leads to another, there's always one more piece of equipment you just have to have. I've accumulated loads the last two years, I could never afford it before so had to make do.
That's my woolshed, except it's proved impossible to keep totally dry and vermin proof. it does though have a heater which helps a bit. OH built it, much bigger than I wanted, but he now has 2/5ths of it and I have the rest. He also has the old stone barn but that is definitely damp to the point that when it's cold and wet condensation forms on things. The new wool shed is a palace and I do have the big Dryas rug loom up there and one wheel, but mainly it's the sorting board and endless fleece. The idea is to sort it straight after shearing but I haven't quite finished from last year. There is a loft but I can't get up there yet - it's a wobbly ladder tied on with rope, and I don't do heights, especially wobbly ones. One day he might get round to steps.
I think my main problem is that I want to keep so much immediately to hand. Certainly my two main wheels live in the house, one in the living room the other in our bedroom. The Ashford loom is in the granny flat, plus storage boxes of fibre and small equipment - to get there though means going outside and along a path - not too nice when it's snowing or pouring so I prefer keeping stuff in the house. The hall gets used for storage boxes and the little Kromski loom, blending boards, combs, hackle, lazy kates, etc etc. Oh and all my spindles are in the dresser amongst the crockery. The house is just too small to have a whole room dedicated to my craft stuff. I think the ultimate solution is for me to stop buying equipment - I've surely got more than I can use in one lifetime. I might sell the art yarn drum carder, which I don't use very much. Now that would clear a huge space[size=78%] [/size]
I'm one of those people who can fill any space with stuff, but I don't suppose I'll change now. It does sound as if I have more of a problem that most, so it has to be me. Okay I'll admit I'm a hoarder
