My favorite Halloween decoration would be the tennis ball ghosts I made several years back. They are kid friendly and easy to make. You just need a stash of old tennis balls!
After finding space for a family time capsule I sealed it up this past weekend with pictures and questions such as: Do you still use credit cards? It is very important to research the type of materials that go into creating a time capsule to make sure in 30 or 40 years there is something to open.
