Things You'll Need
Instructions
Cover a table thoroughly with newspapers to form a work surface.
Cut one cardboard piece large enough to fit inside each onesie, and hold it taut without causing permanent stretching. Place the cardboard inside the onesies.
Let each guest choose a onesie and decorate it with fabric markers and fabric paint.
Cut a sponge into a shape, such as that of a star or duckling, to form a stamp. Dip it into a saucer of fabric paint, and press it firmly onto the onesie.
Cut small sponge cubes to apply fabric paint in freehand patterns or to paint over stencils.
Hang clotheslines in a space with good ventilation. Use clothespins to hang the decorated onesies from the clothesline until they dry completely.
