I don't use buttons very often either, especially in a cluster, but it seems most kits have them. I don't like spoons and other utensils, I find it odd and don't know what to do with them unless I'm scrapping a page with food.
Certain color combinations make me cringe too, I adore the color orange, and the color pink, but not together....ewwwwuck! I would have a very hard time scrapping with them, and yet I see many kits, so I am one of the few that don't appreciate that combination of colors together. I keep hearing my mom in my head saying "you can't wear that, it clashes", lol.
I'm not a fan of big chunky frames either, I feel like it takes up too much of the page.
I think I can work with most anything else. So much easier to list what I like, lol. Good thread
