I'm all manner of things... 
(Or, you can call me pretty much anything as long as it isn't too crude).
The different category may or may not affect your exposure, at this point the idea that listing in different categories will allow for better exposure due to eBay's manipulation / throttling (as opposed to just having more listings with a wider variety) is an unprovable hypthesis (I'm not saying that it isn't plausible, nor that it doesn't have any merit, but it would be very difficult to prove one way or another from the seller's standpoint, simply because if you have a wider variety of items in a range of categories, increased exposure would be expected, and if the items are still actually related in some way, you also get some cross-promotion happening).
I sell jewellery as well, and branched out into craft supplies, so almost all of my listings are in a sub-category of the Jewellery main category (primarily Handcrafted Jewellery, Jewellery Design & Repair, and Fashion Jewellery, but I have the odd thing listed in fashion accessory categories). These are all fairly highly saturated categories, so I've tried to be as niche as I can without being too obscure, and I am constantly looking for related items that continue to expand my range, so a lot of my previous suggestions are the kind of items I look at, too... (But don't really stock as yet, mostly because I've built up a bit of a theme / brand, so I want the things I do get to "feel" in line with that and so far, all the items I've found are either wooden, which I'm a bit reluctant to import, or just a tad expensive for me right now... ).
But, even though in eBay category terms my listings are in a fairly narrow spectrum, and I'm listing in categories with some of the highest numbers for total listings, I have tons of different kinds of items and, although I do have some quiet times (some very quiet times), my store is never really totally dead.
....if that helps, at all. o_O
