Looking on the reverse side of my pillowcase, I wasn't happy to leave all though ends loose. It really only needed the reverse part putting on to finish it off, but I decided to add a sheet of material and outline quilt all the seams.
It might be a bit excessive work, but it will look better and be stronger for it I think. Unlike a quilt that might have batting and a back piece of material, and may only be washed occasionally, if ever, this would need to be washed and ironed. Ironing it would be a nightmare as the seams would take a lot of ironing.
It took quite a bit of time to do but in my opinion looks better. DB commented on how much more substantial it feels.
Here is a close up of the final stitching:
Have a lovely weekend folks.
