Create a plan
Before starting the redecoration process, you have to make sure that you really know what is the next move. So, in this sense, you should create a specific plan that helps you guide and figure out what you can keep and reuse and what you should throw away or recycle.
First of all, you can make a sketch with your ideas and expectations, and maybe it will help you. Your plan should include the size of your garden, your budget and the things that you want to buy and replace.
