Scale Rulers and Charts
I developed PDF files with scaling charts and rulers for people who are not fond of doing division and math in the head. The video below will give you some idea of how my scale rulers can be used.
Use the Scale Chart to divide measurements into 1/2, 1/4, 1/3, 1/5, 1/6 fractions in ether inches and centimeters.
The Scale Ruler file includes instructions on how to make your own scale rulers and use them to increase and decrease patterns to 1/2, 1/4, 1/3, 1/5 scale sizes.
