People are making your monster pants to sell. I was wondering if you would be willing to put your pattern on Craftsy for sale, or Ravelry? That way you would benefit from the sales of your pattern and people would not sell without you benefitting from their use of your pattern. Hope you read this! I had asked in your original blog on the pants for permission to sell, but haven't seen your response. Not sure you are still checking for questions or giving responses, but thought I'd try.
I would also love to make these to sell as I have already had a few requests however I would not breach your copyright without permission. I would of course give credit to you as the designer.
