My search history is clogged with DIYs. Can you change out your kitchen backsplash by yourself? How many rocks do you need to build a retaining wall on a hill? Is reroofing your gazebo with cedar shingles so hard that you really should just give up and use asphalt tiles instead? The internet’s answer to these queries seems to be: You can do anything if you set your mind to it and have a free weekend.
