So the changes I made are to step 9 of the original tutorial & pattern which were posted here. Instead of running these through the sewing machine I hand stitch down the side of each pocket separately.
I know, four area's of hand stitching. I think it is more that I am impatient than lazy that makes me groan when I think hand stitching (Patients - one of the many virtues that I need to work on this Lent.) But, as you can see in these pictures, this give both of the pocket more room to breathe. It may take more time to complete but the results are much better.
Thanks for stopping bu the nest!
