Muffin Tin Caddy: Screw together a tote from three pieces of 1/2-in.-thick plywood cut to fit the width and height of your trays. Screw plywood strips on the inside to act as drawer runners for the tins and glue or screw on a thin plywood back. The tote shown here holds four tins, but you can build it higher for even more storage capacity. Cut the plywood sides long enough so there's room to add a 3/4-in. - diameter dowel handle.
