I changed some things when I made this bag. The directions call for it to be fully lined with a very lightweight fleece and also to be reinforced with interfacing. I nixed both of those because I wanted a bag, not a blanket. I also decided not to add top stitching. The materials are plenty busy and I didn't think the top stitching would add anything in terms of looks or stability. It sews up quickly; I started sewing late yesterday morning and was done by mid-afternoon.
Here's a picture of the lining plus one of the two pockets plus you can see one of my sewing tags.
