Keeps your cookbooks or other how-tos clean! Clear plastic, polyester ribbon and rickrack can be wiped clean of batter with a damp sponge. The components are sewn together, so there will be no issues with adhesives warping the polyesters or dissolving in water. And the apron can act as a bookmark when not in use.
Clear plastic folder, Olfa knife and ruler, polyester ribbon, coordinating rickrack, coordinating thread, cutting mat (optional), awl (optional), scissors. The hardest part of this is finding a folder with enough "flop" to keep the edges down--tho the rickrack does help to weight the edges.
Step 2: Measure and cut "apron" to fit
The "apron" (cut folder) should, when closed, measure approximately 1/2" more than the width and 1/2" more than the height of the book. This catches more spills and allows room for the rickrack so it doesn't obscure the text. This margin isn't so large, on the other hand, that the apron will be shredded by sticking out when the book is closed.
A paper cutter is ideal for cutting the folder super-square, if you have access--if not, a ruler and Olfa knife will do the trick.
Step 3: Round the Corners
Round the corners of the apron with a pair of scissors. You don't want sharp points you could hurt yourself on, eh?
Step 4: Pierce along the fold
Pierce along the fold using an awl or a needle every 1/4" or so. Pre-piercing makes the sewing in of the ribbon a whole lot easier and more regular. Don't make the piercings too close together or too close to the edge, lest the plastic tear through.
Step 5: Prep the ribbon
Cut the ribbon at a diagonal and long enough to extend 4" or 5" beyond the top and beyond the bottom of the "apron" when the ribbon is centered within the fold. Sear the poly ribbon's cut edges very carefully with a lighter to prevent fraying.
