Searching everywhere!
Closets, shelves, heating room, garage and shop. Wa La! I find a packing pad, the kind you wrap refrigerators in to move. Perfect for the padding underneath. Pulling it out of it’s hiding space I get a whif! Peeee Youuuuu! Badly in need of a bath, so another delay as it is put in the wash, and dried multiple times.
Tick Tock, Tick Tock,Tick Tock.
The packing pad is what I use to lay on the seat and measure the sizes, shapes and surfaces by marking it with my good ole sharpie pen. Who cares, about the marks, they won’t show after the upholstery material is put on top.
