It couldn't have been easier. In fact, this project hardly needs a tutorial because you are basically just sandwiching some fabric and ribbon between two sheets of contact paper, however I did learn a couple of things along the way that you might find helpful.
My materials included a piece of scrap fabric, some leftover ribbon, and clear contact paper.
I measured my fabric 1 inch smaller in the length and width than I wanted the finished placemat to be, then cut out a sheet of contact paper slightly larger than the finished size (you'll trim it later).
Peel back the paper off the contact paper.
Oh look, here comes one of the dogs to test it out...
I love when my hard work is appreciated.
