In my past work with plants I have always grown swatches on flat surfaces where the roots grow into a nice bottom layer all feeding into themselves.
I decided that the coming together of both roots and yarn would be grown vertically, so the first experiment starts.
I knit a small sleeves that I filled with seeds.
Yarn- 100% Wool
Seeds- Wheatgrass- Whole Foods (Hard Red Winter Wheat Berries)
