Woodsprite willow starts

We have a plant and seedling swap twice a year. I am currently doing some trail maintenance along a riverbank at a local park. We've been taking the willow cuttings for starting new trees.  I saw this video and thought that with some of the larger cuttings I could knock out some quick woodsprites and offer them up for sale. I think it would be an interesting item to offer. Overwintering the cuttings in the greenhouse and selling the successful starts.
