Isn't this gorgeous. As part of a weekend long permaculture course, we tried our hand at grafting. When I saw just how we were going to do this, I sat back and watched. It looked very dangerous pushing a knife down through the wood in the direction of your hand. Bam, one of my carpool group cut her hand. Bam, one of the men at the class was bleeding. I'm not big on knives at the best of times. Thank you, but no. I'll pass on this one.
