I am not sure that this is a repeating border stripe vs a true border print that runs the length of the bolt printed along each selvedge edge with the blue solid filling the space between the selvedge edge border print.
send a message to the Etsy shop owner to verify how the border is set up. She should text you a picture of the fabric still on the bolt so you can see the border.
