^ I tend to do the opposite. I do about 3-4 colors per thing, and most are throws but simps look good too. I typically take about 5-10 minutes on a sticker, and about 5 a day (currently have about 85 stickers). I think if you just make a bunch of slaps and put them in places you can't paint, and then paint everywhere else, you'll be noticed more also. I actually really like hand drawn stickers, and not the "made on the computer" ones, since they just don't seem as special to me and I tend to think it's a band sticker or something.
I like to do the same thing. I'll do 3 or 4 colors and I'll spend a few minutes on them, depending on what I'm doing or how I feel. I like to keep it simple looking, nothing complex. Crisp and Clean slaps draw looks, not something no one can figure out what the hell it is. My stickers are for the people in general...sometimes I draw "hate" stickers for things...like a damn vending machine that eats my money always. Location is KEY. A nice little sticker when you flip up the toilet paper holder that'll make you pause to read or look at and say...that looks cool. That's just my view on stickers.
Might have been said already..... You ever get those stickers with the backs that don't want to peel off and you're in a hurry to slap it somewhere?? Never fear! With a little invention called tape you will be worry free. Stick a small piece of tape on the backside corner of your slap (if you're using a postal then this doesn't apply) and make sure a little extra hangs over. Next fold the excess back onto itself so you got a stick-free handle to pull on. Works on a lot of do-it-yourself stickers but not all.
I had a buddy that used to order the pink triangles and rainbows stickers and he'd put'em on cars of the people he didn't like.
MUAHAHAHAHAHAHA!!!!! The post office must've ran out of priority stickers so they went through their storage and brought out the Old School stickers. I TOOK THEM ALL! Going back again to see if there's more and I'll go every day after that until I get'em all (like pokemon).
