I inserted two invisible zippers to create pockets, and by folding it over two more pockets are created. I have zero dressmaking skills but this brilliant tutorial that I found on youtube made the process foolproof!
It took awhile for me to figure out the design and dimensions on paper but I'm very glad that I took my time. It turned out just how I wanted it to, the sewing came together easily, and I conquered my fear of inserting zippers. I got to use two sewing machine feet that I hadn't used before - invisible zipper foot and variable zipper foot. I'm quite pleased with this so far:
