Hobbies are definitely not dead. For years I've been making wooden toy trains and have more recently made other items such as Noah's Arks with 12 sets of animals, manger scenes, animal silhouettes, and other things. We sell them once in a while at craft fairs which is fun. It's all in fun. Not work really, where it's nose to the grindstone.
One other thing that sells good is tractor trailers with different attachments such as a flatbed, a logging attachment, a tanker attachment, and a box truck attachment. Sometimes I even give them away, it's just a lot of fun for us.
