Description

Title: Add Sticky Post to Storefront Home
Description: While WooTheme's Storefront theme is great, the sole focus on product on the homepage doesn't work for every site. This customization allows Storefront users to add a sticky post to the bottom of the homepage.  

Objective: Add a sticky post to the homepage of the Storefront theme.
Goal: I'd really like to contribute this an extension for the WordPress repository. This is very much a first attempt, it works, but it's got some deficiencies.
