Fitted and loose covers for a two seater sofa

All the details

We have recently had new covers made for a Laura Ashley sofa. The old ones were in good condition but didn't match a new colour scheme. I have attached a photo of the sofa for perspective. The loose seat cushions are 27 inches by 25 inches; the rear loose cushions are 33 inches (widest point) by 21 inches. The cover for the sofa is fitted but the dimensions are approximately 72 inches wide by 36 inches deep. The material is light green with a dark green and yellow stripe. Perhaps a project for a person with tailoring skills to re-upholster a sofa or to cut up the fabric for other purposes
