My husband used to think 500+ was too many, so I gave a few away (about 40 I think) to the local hospice shop. Most were aluminium, so no great loss, but they were gone within a week.
I think I have around 480 right now, but we have a large double garage, so I can display quite a few (the best ones of course) on the walls. I also have two clothing racks, that take 70 frames each. One is for woods, the other for graphites. The rest are tidied away in a large bin (around 120 there I think).
Plus I have all my new frames (new, old, if you know what I mean) on the shelves of a bookcase and a few more hidden away in a large chest of drawers. Oh yes, and some in a cupboard....
