Where did you find that price listed for velcro? Was it a velcro kit for consumers that included pre-cut squares? McMaster-Carr sells five foot by one inch lengths for only a dollar or two more than your list price, and that would be enough to produce many units.. When dealing with such a low cost item to begin with isn't some accuracy required to fully understand the margins of producing the thing?
