Sorry but I couldn't find an e-mail and did not know where to leave this message. I found your proportional scale on the web and would like to thank you! I am an artist and even though they have the hand-held ones, this will make it so much easier when I want to create a large canvas from a small study. I am going to add the link below to my website for other artists to use.

Thanks Again! monica
