read the MIT guide, the FAQ's and watch the animations on howstufworks about lockpicking, that should give you a fair bit of information as well as searching the site.
there are loads of things you can ake tension wrenches from, search for home made picks, it should turn up loads of stuff for you. things like the metal parts in car wiper blades and hacksaw blades tend to be the most common, but as for things around your dorm room, it depends what you want to pick, you can get a womans hair grip and snap off the wiggly bit leaving an L shaped piece of metal, but they only work on small padlocks. you could try using the metal shirt-clip part on a pen, i think Parker pens work well for this if i remember right (they're the ones with the arrow shaped clip just in case you're not sure

). just have a look round for anything about 2-5mm wide made of thin metal and see what you can make from it. you'll be amazed what you can do!
welcome to the forum by the way, i hope you like it here, good luck with you're picking!
