Bright Green Cotton Cushion Cover (DB11)
100% cotton cushion covers with a hidden zipper.
Cushions are hot, hot hot right now and these are amazing quality.
All square cushions - 45cmx45cm in size. 45cm = 17.7 inches.
I use a 19x19 insert inside but I am positive a 18x18 would also work. Of course this depends on the quality of your insert and the amount of 'puff' they do vary.
