Dacron is a must have for all seat cushions! PLEASE READ! Dacron makes your cushions softer, fills corners and gives the cushion a nice crown instead of looking flat! When using Polly Dacron it is suitable for both indoor and outdoor cushions. Make your cushion cover to fit the foam before you add the Dacron! DO NOT make an extra sewing allowance! The purpose of Dacron it to over stretch and fill the cushion and adding additional sewing allowance will defeat the purpose.
