Hey, one thing we could use would be a generic pile of rags/clothes.
To be used for armor, clothing, and everything that can be grouped there.
That's also boots, gloves, hats... but I think a bundled up cloth would work.
Curse you! I've been putting off this one because its so many different things! I'll have a go though, the current one is looking more and more out of place...
Maybe it could just be a generic sack looking thing? I mean, if you're gonna carry around a pile of clothing you're not gonna be, like, holding a shirt at arms length...

Plus you could use that same sack for other, you know, sack-ish things, or just as a generic "this contains various objects" tile.
