Placemats For Round Tables

Investment wedge

Make a model for you. Figure the width of the mat will then taper up, probably 2-3 inches on each side shall operate. Just for fun to do yourself a newspaper and cut the model base and cone that you want and keep it until you get the measurements you want. If you do it this way to cut the paper in the amount of seats you will need it and place it around your table and see if it woks or if you need to increase or decrese the cone at the top. Since you're sewing it, you have a model to work with, but remember to leave 5 / 8 "for sewing.
