Thank you Lynn and David, here are my recent ones. Although they look fun... danger lurks. I drilled holes in these to late in the game, or my curing was too cold on first day? I do not know what happened. Outside and in are hard as steel but when I drilled my holes for drainage the insides were dust? Whaaaaa? Dust.....? Ya, dust surrounded by harder than can break outside. ?????? They are all keepable for me and should last a few years but what the hay? I lost around 8 pieces to not really knowing if they are trustworthy. Oh well. Time to buy another $9 sack lol....
