Easiest Most Realistic Faux Rust Paint Technique

This week I'm super excited about our project!  We're making it a Technique Tuesday, but on a Friday!  We found this great looking vintage sign on Pinterest and I really wanted to keep the age and rusted look!  So we did a little research and learned how to make faux rust with a little paint and sawdust!  Faux rust that looks super real!  We had some hiccups along the way and it was my turn to be the skeptical one, but it turned out beautiful!  #doitbuilditmakeit #kimandgarretmakeit #DIY #rustic
