If you are sewing a waterproof Kelly Anorak, we’ve created a free pattern bonus for you! While we love the roomy design of our gussetted pockets, they may collect water on very rainy days. For our blue sample in this sewalong, we added an exterior flap to the pocket to create a completely sealed and waterproof pocket. If you’d like to do the same, you can download the modified pattern pieces and instructions here. While we don’t have step by step photos for this pocket, much of the construction is the same as the regular gusseted pocket, so please refer to that post if you need a little extra help.
