A simple Sketch file we use to jumpstart our UI design projects. It contains color swatches, type styles, buttons, forms elements, and a grid. We tried to keep all styles fairly generic, with the expectation they will be personalized to match your project.
To view the toolkit as intended you will need two font families, Open Sans and Merriweather.
Download the UI Toolkit and use it on your next project.
This is a work-in-progress and feedback is much appreciated.
