Good evening, Supastar!
My favorite oil blotting sheets are the Boscia Green Tea Blotting Linens. There are 100 sheets in a box, and the papers are preservative-free, oil-free, and free of parabens and sulfates. They are perfect for sensitive skin and will blot excess oil without changing the color of or removing your makeup. You can learn more about them here: http://www.sephora.com/blotting-linens-P61217?skuI
Clean & Clear are basic, affordable, and get the same job done as other more expensive brands. Even the cheaper generic brands work just as well.
However, if you're in a super pinch and don't have any oil blotting sheets, go find your nearest bathroom and swipe one of the sanitary toilet protective covers and use one of those to blot. I know it sounds super gross, but i've met a couple women who do the same thing and say that it's just as good as regular blotting sheets when in a pinch (I guess if you're super desperate!)
I like the Up&Up blotting sheets. You can find them at Target next to the Clean and Clear blotting sheets. Same exact thing but a few cents cheaper! I hope this helps and good luck!
