Cut out the Cookit shape and slots
Cut out the Cookit shape and the two 60º angled slots in the front panel. Be sure to make the slots narow so the 76º angled cornwers from the back panel fit snugly to hold up the front panel.
Score the fold lines
With a blunt edge, such as a spoon handle, score the fild lines. Make straight folds by folding against a firm straight edge. Only score the oprional fild lines if you intend to fold the Cookit for compact storage.
Glue foil on the Cookit
Using a paintbrush, spread the glue/water mixture on the dull side of aluminum foil and press the gluded sheets of aluminum foil tightly and smoothly like wallpaper onto one entire side of the Cookit. A few wrinkles won’t hurt.
Leave flat until dry. Trim any excess foil.
