# Matt Warcholinski

Runs PhoneCaseInserts, a free, non-commercial project, from Poland.

## What I do here

I build the [insert maker](https://phonecaseinserts.com/create) and the [phone templates](https://phonecaseinserts.com/templates), and I publish the guides under [DIY](https://phonecaseinserts.com/diy) and [ideas](https://phonecaseinserts.com/ideas). The site started when a child cut a paper insert for a parent’s clear case, and it grew from the practical questions people ask when they try the same: does it fit, will it block wireless charging, which paper works, how do I cut around the camera.

## How the guides are made

- **Sources are opened and linked.** Each outside fact links to the page it came from, with the date it was checked. If a source could not be opened, the guide says so.
- **Tested and untested are kept apart.** A number is only called tested when it was measured. Manufacturer sizes, estimates and one maker’s claims are labelled as such, and each guide says what it did not test.
- **I publish and answer for every guide.** If something is wrong, it is my job to fix it.
- **Pictures are labelled.** Illustrations and AI-generated images are captioned as such; real photos are marked as real.
