I would say " beautiful trays from wood" :)
You are right the wood is beautiful. I will add that the trays are equally beautiful.
You are lucky to have a whole walnut tree for yourself. Walnut is expensive now, at least in my area. 4 to 5" $8/bf. $12 for the wider boards. That’s $3/bf more than June prices.
I wish I had a bigger shop where I can stock up when prices are good.
