S.T.
15 month old babies don't have the fine motor skills to do crafts. The can do handprints (with you holding their hands) or smooshy paint all over the place. Maybe place cotton ball tails on a pre-glued bunny that you made. but at this age the moms really do the craft and the child's hand is moved around.
Wait another year. At this age I would sit at the tiny table with my little ones and we'd color or make towers from legos. anythign else disproportionately too much time making up and cleaning up and very little time actually crafting...
