Magna-Tac is a permanent adhesive that contains acetone, so it's a bit smelly. If you are making the puppets with children, you may want to do the gluing yourself. This glue is washable after it has dried. If you are making the puppets for very small children, sewing the small pieces onto the mittens is best, because if small children put the mittens in their mouths, pieces could come loose.
For the cat: To make the cat's whiskers, use a needle and linen twine. Pull a length through the mitten near the cat's nose, and tie a knot at its base to secure it. Repeat two or three times on each side of the nose.
For the dinosaur: Be sure to use a glove, not a mitten, for the dinosaur. The head should be glued to the middle finger of the glove. The thumb and pointer finger on one side, and the ring and pinky finger on the other will act as legs and feet. Attach the feet (see template) to the ends of these fingers. The pointy spine should run from the center knuckle back over the center of the wrist.
