This Gilford mason/artist has several of his works included in an exhibit at the Boston Flower Show. We went yesterday. I don't know anything more about him but his work was beautiful.

PS: If any here were thinking of attending the show, don't bother! Terrible waste of time and money. Two or three nice displays at the entrance. Then booth after booth of the same crap you see at craft fairs all over The Lakes Region all summer (most having nothing to do with flowers or gardening).
Never again...
