Step 2: Prepare your milkcrates
You could decorate them using paint, but you could also leave them the color they are, especially if you have various bright colors.
A note on composting however: black will generate more heat that will help the compost and speed things up. But it is not as pretty...
I decided to use two black ones and one red to add color
Clean them with a rag.
Cut pieces of your screen/mesh or weed barrier fabric and hot glue gun them inside the milkcrates to cover the side holes. This will keep your compost inside and prevent pests to go in, but air and water to circulate. I had leftover of weed barrier fabric that I used for my square foot garden, so I used that, but you could salvage some mosquito net from a tent or an old window that ended up in the trash.
