See the creative side of concrete while learning how and why this ancient building material has stood the test of time. Through easy hands-on projects we'll discover all kinds of ways to bring concrete into your home and introduce an industrial chic that goes with any style.

Using no special tools or equipment, you'll be able to learn the fundamentals of working with concrete to make smaller crafts using standard molds, molds with voids, and custom molds to make your next concrete creation.

There's more to concrete than you might think, so follow along and make something you'll be proud to show off at home!

Mike is a self-taught DIY troublemaker who loves to get dirty making. Making concrete creations can be a messy endeavor, and there's no other way he'd have it!

Outside of the shop Mike has designed and built hundreds of prototypes that explore the intersection of functionality and whimsical absurdity, from chainsaw blenders to successfully melting metal in a microwave (though, that project eventually caught fire).

His work has been featured all over the Internet, in print media in all kinds of languages, and even on Japanese television. When not getting his hands dirty building, Mike is a published author and video maker.
