12. Make a Garage Play Space
If you have a garage, you can use it as a playground for your children. However, you have to clean everything very carefully. Items can be stacked or placed on plastic shelves.
Besides, garage space can be used as a gym. If you don't have a big backyard, it will be helpful to provide your kids with a play space. Your children can play without bumping into furniture or breaking anything. What you need to do is your time and patience to finish arranging this area. The best thing about this project is that it's completely free.
