I've been attempting fruit leather lately. After a couple batches my biggest problem seems to be spreading the pureed fruit evenly so that it dries at the same rate. Next time I may use two cookie sheets. Otherwise it is a pretty foolproof process and the end result is every bit as good as the store bought stuff, without any of the extra sugar and junk.
Here is a photo (and instructions) that inspired me. And one other tutorial here I used as reference although there are about a million more to be found, I'm sure.
Also, do not use wax paper. It sticks. Next time I'm trying parchment paper or buying some silpat. Hot fruit on plastic wrap scares me.
