What do ya'll bake your cupcakes in? I use the typical Walmart or grocery store papers, and they just seem to flimsy to me, and the oil soaks right through them. I want heavier weight ones i guess, to look more professional.

They now make greaseproof ones which are of a heavier weight and you don't get those oil stains. Or you could use foil...they come in a bunch of colors as well. If you got to Global Sugar Art and search grease proof a bunch come up.
