Wow! I haven't looked at them in a while. Last time I thought they were $99.
If it is in really good condition, I would price it at about 60% of retail. That would put it about $100.
Another project done. Took longer because I had family in for a week. Judy Gale Roberts pattern. Woods used: Aspen, Poplar, White Limba, Butternut, Walnut, Maple Philippine Mahogany. Finished with two coats of Walrus Oil. Aprox 18" x 22".
I don't know specific %. I recall just tracing the card to create the middle layer. It has been a number of years since I made them. Another item that didn't sell well for me!
