Materials
Paper grocery bag, scissors, stapler, crayons or paint, yarn
Procedure
If your bag has a design on it, cut lengthwise along one seam so you can turn the bag inside out. Unfold all creases outward and flatten bag. Keep the bag folded in half, and trace the pattern onto the top of the bag, so that the top of the bag becomes the top of T-Rex's head. Cut out the pattern through both halves of the bag.
Staple down the front of the face, and down the back of the neck. Color or paint your dinosaur and add eyes, teeth, etc. Stuffing this mask is not necessary. Punch two holes in position above the child's ears and insert enough yarn to tie under chin. You are now ready to have some fun - maybe even do a skit about dinosaurs!
