Hey,
I use white and manilla colored envelopes that can be purchased for very low prices at stores like walmart. You can find pens, stationary, and things of that sort at a dollar store. I started out using stationary, but now I just use plain white filler paper. I sometimes decorate the margins with stickers and little notes. You have to search around on the internet for large pictures to print out on 8x10 paper. The high quality glossy paper can be bought at the dollar store too.
I think this is one of the best celebrity sites out there. The admin keeps up with it daily and there are thousands of up-to-date addresses. There are a few other sites though
http://www.autographsuccess.com
I joined that a while ago, but its not very active.
and
http://www.mailhollywood.com
that site is just OKAY to find addresses on, but the forums are totally out of hand and so is the little chatboard on the home page. That site is not kept up with at all.
well hope this helped! Goodluck, and dont hesitate to ask anymore questions
