There a misnamed product called hardware cloth which is not cloth at all, but metal
mesh with 1/4" square holes, perfect for sifting soil. Call some real hardware or
farm supply stores. You'll have to build a frame out of wood and staple or screw
the cloth to it. Your imagination should tell you the details.
