You guys might want to try making mushrooms from green wood. Yep, we know they're gonna crack, and sometimes that's where the uniqueness comes in. You just don't know where the cracks will appear or how severe they'll be. Try turning 14" of green wood (about 6" thick) into a mushroom and put it aside for a week or two. If it splits OK then drill eyelet holes down either side of the crack, and criss-cross a leather shoe-lace through the holes. Very effective - and a good seller!
