Another project I freelance worked with Lowe's Creative Ideas team on is in the latest issue of the magazine! It's called 'stone bath mat' and the directions are right here.
I thought they did a great job with it when it came to executing it for the magazine feature. When I developed it, I did it with a rubberized mat as the base rather than the shelf liner they used (but there may be a good reason why they changed it). This shoot shows it as a bath mat, but it's also great as a welcome mat by the front door.
