At church we have had the same display for a number of years. I suggested we could have something different, and was asked "Are you willing to do it?" People were surprised when answered in the positive.
Card frames were made, and a sheet of clear cellophane placed on it. Then the children from Junior Church added squares of coloured cellophane on top. They were attached with a re-positional spray adhesive. Another layer of clear cellophane was added to keep it all in place. Then the black paper silhouettes were added.
Many people have made favourable comments. One of the members of the congregation has expressed an interest in doing a silk painting for next year.
