Order a single opening mat (opening size does not matter) in your desired quantity and add this fee. Select the total number of openings in each mat and and enter the quantity of the mats to be cut. At checkout leave a note in the comments that a mat is multi-opening and which one if you are ordering other mats.
After you place your order send us an email with a simple drawing showing the orientation of the mat, the orientation of each opening, the opening sizes, and the borders. *We will cut the mat window openings to the EXACT measurements you specify.*
