Have you tried a curved waistband?  That eliminates a lot of back gape.

No I haven't. I'll look into that. Thanks for the idea.

Fabulous @Ouryve - such cute foxes!

Sew Ruthie Sews' entry #3 A Whale of a Cushion
I made a large cushion for the sofa. It uses panels from a rather flimsy cotton bag from Whale and Dolphin Conservation and some fabric in a whale print. I interfaced the main graphic panel and added blue textured flanging and then the whale print fabric. For the back I used some plain blue fabric and added a button closure.
As this came out a unique size, I also made a cushion insert which I filled from 4 smaller cushions.

Looks really good @Sheilago

All done. . It actually needed 5” off, so I cut off about 2.5” , then pinned up 2.5” more , ironed it and pinned it , then sewed all around with stitch 8 the stretchy zigzag. After that I trimmed it close to the zigzag, which is a great tip. The sewing went really well, however the original cutting off of the 2.5” was tricky as the manufacturer (White Stuff ) wasn’t too fussy about keeping the pattern level on the patterned fabric. As you can see the line of flowers is way off,  but I had to go with what was already done or it would have been an uneven hem. Also a bit big for a 14 , but I’m not taking it in. It’ll be fine for a hot day if we get any.
