Father's Day Shopping: Tarps

So I've started shopping around for Father's Day gift ideas. My dad is super hard to shop for, so I'm constantly on the lookout for things that I think he might actually need or want, and I'm willing to think outside the box sometimes if I have to. That's the reason why I'm currently browsing a website that sells nothing but tarps.

I guess that requires a little bit of explanation. See, my dad has been really into doing projects around the house lately, including painting the guest room and some other spaces in the house. The thing is, knowing him like I do, I'm sure that he's doing it using a "dropcloth" made out of old sheets or a plastic shower curtain or something. So I was thinking of getting him a real canvas dropcloth that he can use for all of his painting projects. That way, he can focus on the painting part without worrying about whether he's making a mess out of the floor.

While I'm at it, I may also get him a couple of heavy duty silver tarps that he can use for any projects he does out in the yard or garage. These things are resistant to just about everything - water resistant, mildew and rot resistant, acid resistant, alien attack resistant (just kidding on that last one) - so I think they'd be great to protect whatever current project of the moment he's got going on outside.

Anyone else have people in their lives that are hard to shop for? What creative gifts have you found?
