A nursery was putting on a play and the children are dressed up as the sun, moon, and stars. Is making childrens costumes (3 dimensional items) made to look like these creations a problem based upon the Pasuk in Yitro and Gemara about not making these images or is a child’s costume obviously not a “real looking image” unlike perhaps a drawing or a sculpture?
There is no concern for prohibition in making a costume.
The prohibition of making a model of the sun, moon and stars applies specifically to a sculpture, and according to many even to a flat representation.
It won’t apply to a costume, which is distinct from forms that represent the celestial bodies and can be related to idolatry.
