Kettles and other seldom-used utensils stored on high cupboard shelves are reached easily with this double-duty stool, which opens up into a sturdy 40-in. step-ladder. Except for the seat, plywood may be used entirely or combined with solid stock. Run the grooves for the treads in the side panels ﬁrst, then tack both together and saw out the section that swings up on top of the seat. Glue and screw the treads in place and hinge the two-part seat to bring both sections ﬂush when folded. Rubber-headed tacks will keep the stool from slipping on waxed ﬂoors.
