Prayer baskets are used by some witches. They would take the person's help for assistance and write the request on a piece of paper and run it through incense and put it in the basket. Once a month the witch would go through the pieces of paper and burn the ones that were answered and re-empower those that didn't.
I've always read the burning of the paper to be a way to release the energy into the universe or bind it if one is trying to seal away certain thoughts.
I would probably put the notes in a basket with herbs whose energies go toward the goal of what is written on the paper, or in general furthering along a goal, to wich I would dedicate the basket specifically for that use.
This has nothing to do with requests but it's kind of the same, when I want a question answered I usually put the question on a piece of paper and then before I go to bed I say 'answer this question truthfully, hear my request, so mote it be'. Most of the time it works but try it out for yourself!
