Measuring Tulle to Determine Width
Formula Step 1 - Multiply height of favor by 2
Step 2 - Multiply width of favor by 2
Step 3 - Add the sum of step 1 and step 2
Step 4 - Add an additional 6" to the sum of step 3
The sum of step 4 is the width of tulle required for the favor. (Always pick the next larger size.)
Example

Calculation
Step 1 = (Height) 2" x 2 = 4"
Step 2 = (Width) 3" x 2 = 6"
Step 3 = 10"
Step 4 = 10" + 6" = 16"
18" width tulle is our next size up.
