Restore or Build Your Own Furniture
Reddit user thefingolfin says:
"I've recently started getting my feet wet in some DIY projects . . . I build a headboard for our bed for under $50. A friend gave us a large wooden spool that my wife and I are going to convert into a table/bookshelf combo. With a few tools and some time, you can save hundreds of dollars and have the satisfaction of building things yourself."
