Making Geese in Any Size, The Formula:

You can make your Flying Geese in any size using the following formula:

Size of squares = 1/2 inch larger than the desired finished height of the overall unit.

Height of the rectangle = same as the squares you cut.

Width of the rectangle = width of square times two minus 1/2 inch.

In other words, if you cut 2" squares, you would cut the rectangle 2" x 3.5"
