8" Proportional Scale

This device allows for the perfect scaling of any photo or drawing to exact proportions without using a calculator. To use, set the inside dial to the size of the photo, line up the outside dial to the new finished width of the treatment, then measure all the various long points, short points, jabot widths, etc. and translate the new measurements. The 8" Proportional Scale works with any size photo or sketch and accomodates treatments that are up to a 100"-wide. Instructor Margie Nance uses this handy tool in her Creating Custom Patterns class at The CHF Academy.
