I have made several things from Pokemon costumes for my grandson to costuming entire plays for our local theater group. I've made new bags for lawn mowers and monogrammed silk shirts for the local gypsy leader.
The thing I think was the strangest was a cold weather camera cover for a Hollywood crew that was shooting a movie here in the winter. The camera kept freezing up on them so I got out my window insulation and designed an insulated cover for the camera that would keep the cold and the snow out. I made the lens cover with clear vinyl and made it with velcro so it could be removed for the actual shooting. I had to create the pattern myself and was totally shocked when a month later I received a check for $250 and a request for a dozen more at the same price. I was so tired of making them after the 12 were done that I sent them my pattern and told them their prop person could make them.
