Afterwards I explored the net about interfacings, and came across this very useful post at You Sew Girl comparing Vilene to Pellon interfacings. This would have been useful before I actually started...also saw that she combines interfacings for making bags which I probably should have done for this one to give it more stability.
Guess I will have to make another one to get the structure right.
Also, when I took my sewing machine in the other day to have the tech look at my backwards stitching, I got talking to the owner about zippers. Incidentally there was nothing wrong with my machine...seems I am going through a period of being at war with my machine. This does happen from time to time.
Anyway, the owner introduced me to invisible zippers and send me on my way with a folder of instructions to try out at home. Good thing the folder had actual step-by-step samples which was brilliant as the written instructions were hard to follow (I am not a sewer so sometimes do not understand the words that are used).

Again, after I had done all this I came across a free Craftsy class 'Mastering Zipper techniques'. Will have to watch this and hopefully pick up a few tips in areas where I struggle, i.e. sewing a straight line next to the zipper teeth.
