Serious props to Jenise who made--yes, MADE--this concrete vanity countertop with an integral sink. Of course, she had to make templates and build forms first (pictured below). If you're wondering how she was able to get such stunning results, that's because she took a 3-day course teaching concrete artist techniques before she started. Lucky for us, she shares the what she learned on her website, DIY Fun Ideas.
