Louis, The short answer is ?No? I?ve never considered making an instructional Video; there are some very good books, videos/DVD?s and Kits, with everything required, available already, describing the steps and contouring methods required in making an Intarsia and I?m afraid anything I could add would be redundant.
However, I would be more than happy to try and answer, or offer advice, on any specific question you or anyone may have.
