Now that I have a whole afternoon of sewing machine experience I'm branching out into bigger projects. You know, like making bike frame bags. 
LearnMYOG sells patterns (plus free ones) and videos talk you through how to sew all of the elements.

Six Rolling Wheels sells completed bags, their videos more meditative.

Here's a couple of free plans. Running belt would be a good one to try first, nothing extra just a simple belt for holding the phone. Maybe replace zipper with a tab of velcro, since I want to quickly grab/stow the phone to take photos.

@jerzone Now that is an really cool website, thanks for the share - I have saved. Also found some other projects there that look good to try, though sourcing the right fabrics locally is the first step
