Oh Les, can be the thing with Holly, not sure as to how it should be stored, must be able too, the first I was given by a colleague, I turned most of it green as mushrooms, but a pair of candle holders as a thank you gift, they left them in the carrier at work for months, forgetting to take them home, I checked one day on them ... gone black and furry ..
..
Had my eye on some Holly that had been felled to clear for the harvest of other timber, not been up to check what it's like, most do if we have fine weather again, bit of a walk to the woods... and should you try an leave the car near there .. walk back.
You'd found the post handy, I thought the thin wood sheets, inlay or fillets, the glues and a few other things, need to check prices.
Cheers Dewi
