This is a list of items that we are currently collecting. I hope to update it regularly — adding new items when I think of them and deleting items when I have too many. I’ve also set the page preferences to ‘allow comments’ so if you have something that you don’t know if I would like — just leave a comment and ask.

A joy to read!
Do your parents actually help you collect these things?
Yes, they have occasionally brought me things from the list. Some of them bring me numerous items that they have found that are not even on the list but the parent thinks I may be able to use.
