Set the card flat in front of the child. Open the sticker pack and fan a selection of shapes out nearby so they can see the options.

The child peels each sticker, which toddlers can usually manage with a little encouragement at the corner, and presses it onto the card. Start with two big circles for eyes to anchor the face, then let the child add a mouth, nose, hair, horns or whatever pleases them.

Press each sticker down firmly so the edges do not curl. The monster is finished when the child decides it is. No drying time needed. Slide into a clear plastic sleeve or folder to keep it flat.
