It's day three of my whirlwind adventures in guest blogging here on Curbly. Today, it's all in the details...of home decor, that is. Sometimes in DIY home accents, it isn't about the big, striking pieces. Often, it's the lovely, custom details that add up to make a space. Like these DIY coasters. They can be any color, and the watercolor effect is both elegant and whimsical.
