70x40cm, 6mm thick, birch plywood board, which serves as a base for knitted basked for various purposes. Holes ar 8mm diameter, center is 1cm from board edge, space between two centers is 15mm. I measured and marked holes than drill them on drillpress. No finish.
Interesting. Saw something very similar last weekend where the holes, much smaller, were then used to sew the piece down as a lining in the base of a box
