Hi Chris, Hanging signs with saying is a good idea and stencils are readily available about anywhere.
Hi there! It depends on what you're looking for...decor, furniture, garden decor, storage. You can peek at this link to look at some of the ideas Hometalkers have come up with from wooden turkeys to small tables. https://www.hometalk.com/search/posts?filter=small%20wooden%20pallets
Pallets make great rustic-looking projects! I've used them to make signs, planters (for various vegetable plants and herbs), clock bases, table tops, etc. There are so many possibilities! I hope this helps!
