I reuse my plastic cutting mats for lining the wire rack shelving in my laundry room. They help me keep small items in place and prevent bottle from tipping over. They are like a drawer liner for the wire rack. I love them.
I will remember this idea for using them for templates. I used to use the bacon insert, but we quit eating bacon! Thanks to all of you for all your clever ideas! Few items are one-use items any more. Creative minds put then to good use. Keep those ideas coming!
