You don't need a piece of formica for your dining room table. Formica can be pretty skinny, and it presents storage problems.
Instead, try a length of heavy duty vinyl that you can buy at Joann's, etc. My dining room is my sewing room (in fact, I don't even use it for dining anymore on holidays -- too much cleanup to do!
) I keep my table covered with a piece of this extra-wide vinyl. Don't use oilcloth because it is too thin. Use the vinyl
It is also useful when I machine quilt because the quilt slides on it so well! I turn my sewing machine around so the back of my cabinet faces the long side of the table, and let the quilt drape onto the table. It prevents a lot of drag on the quilt.
