I need to get the 4mm ply out of the house, before the better half beats me with a stick. So, I started on the cutting out of paper, and spray-mounting them to the wood. I've actually cut them all out now, and am just fettling the edges for neatness and accuracy.
Thistle added for scale! There are actually 3 more formers on another sheet that didn't fit on here. So far, so good.
