Sometimes I use my phone

The sleeve that fits over cups from coffee shops works great, too.

I use motocross stickers. With the backing still on of course.

Sooo I'm guessing you guys are the type that dont dog ear the pages? Is that what you're trying to tell me?

I also shove pencils in as books marks, and once, I used a light bulb.

Mine is always sheer memorisationumber because I always forget to put a bookmark

I always grab a bunch of bookmarks from the media center when i check out new books, but i never use them

i use old receipts

I've used about 99.9% of these.

cellphone is a great option and remote control

Bookmarks etc. annoy the hell out of me so I use memorization.

I just tear off the corner of a random blank sheet and shove it in
