Pocketfolds

So I am still thinking of doing pocketfolds but I don't want to spend a lot of money.  I mostly just want to keep things organized when I mail them out.  So I think I am going to get a panel pocket from http://www.cardsandpockets.com/.  I can slip everything in there and then just mail it out.  They are also only 47c each so getting 100 of them will be under $50.  I'm under in my budget so far so I have the money.  I'm also thinking of getting a backing for the invitation but I have to see about that.  I might just buy the paper and do it myself....it will probably be cheaper that way.
