Now Playing: Pick up a proportional scale and give it a whirl
Here's a handy tool to have in your craft supplies...a proportional scale. There are three ways to use it:
1-When you have a picture or pattern of a given size and need it to fit in a smaller space. Find the measurement of the original on the inner circle. Rotate this inner circle till the starting measurement lines up with the desired finished measurements on the outer circle. Now, in the little 'window' you read the percentage reduction and this is what you will set on your copier.
2-When you have a set of instructions that are larger than you want to make. Line up as above on one known measurement and you will be able to easily find the matches for each of the subsequent parts of your instructions.
3-When you have a pattern that says to enlarge 125 percent you can tell what the finished size will be. Line up the line above the 'window' with the stated percent enlargement. Now look at the original size on the inner circle and you will see the finished size directly above it on the outside ring.
You can pick up your own proportional scale at photography, craft, and art stores for just a few dollars.
