Q. Where in the world can one find terracotta clay in powder form ? Thank you. Elaine
Q. Exactly what kind of clay do we need to look for [to make seed balls] and do you have any ideas where to find it? Missy
A. You can purchase a lump of “sculpting” clay from a local art store. (Or you can use local clay if you find some.) You then dry the clay, grind and sift it to remove large chunks.
