Roll of burlap (enough yardage for the size you need)
White netting material
Your usual crafting tools
Step 1: Cut out Your Rectangle/Square of Burlap
Here you also have to options. If you are worried about a frayed edge due to the cutting of the burlap (this can happen sometimes) - then this is where your white netting can come in handy. Prepare some netting to be one or two inches larger than the perimeter of the shape you have.
