Your wallet is absolutely beautiful. I love your fabrics.
I, too, have made many of these wallets and the easiest way to do it, is to use quart size ziplock bags, mark them 1-9 and as you cut your pieces, put them in the appropriate bag. You will start sewing with bag 1 and continue in order. You can pre-iron your interfacing ahead of time, too. Lee Fletcher is the pattern maker and is a wonderful woman. She has her own website and you can leave questions for her there...www.pat-e-patterns.com
Best of luck with your future wallets. Please be sure to post pictures, too.
