This project was inspired by this spill mat I saw on She's Kinda Crafty. I don't have any oil cloth at my house but I do have TABLECLOTHS!!! I cut a rectangular piece 42x26 (the 26 is the width between my tables legs). I wanted something that went under the table a bit because my little girl has a tendency to throw things under the table.
This is perfect-less sticky, crumby mess on my floor. I can just fold this up and shake it out outside and it wipes up super easy.
