Stash woes

I have two spare bedrooms that I use as "studio space" although I don't actually work on anything in them. They both are a hodgepodge of fiber, fiber equipment, books, etc. I'm trying to figure out how to make the yarn more accessible, but am not having much luck because there is simply TOO MUCH. And I keep spinning MORE.

My granddaughter doesn't stay with me much anymore, and it is just as well, as this is "her" room:

Closet is full

Handspun, roving, acrylic, a toteful of material

, 

Needle felting, carpet warp, books, magazines, notebooks, etc.

Even the bed is covered

One problem is that I tend to find a pattern I want to make, then end up buying *more* yarn because the yarn I have won't work with the pattern. Perhaps I should look at the yarn first, then find a pattern it will work with. At least until I run out of yarn?

Dyeing: Running skeins of yarn through the amaranth bath. Created a rudbeckia dye bath to use with iron-mordanted yarn, and iron-mordanted the yarn.
Knitting: Finished the Kit & Caboodle tote, except for the blocking. Decided I'd better get a move on regarding xmas socks - the holidays will be here before you know it

That is another issue: I can knit, weave, crochet things... but not everyone I know is interested in being on the receiving end of these handmade objects. The guilds have opportunities to sell items, but only certain items (like amigurumi animals) sell well, at least around here. What to do, what to do?
