Working in a fabric store and helping people choose fabric on a regular basis I'm always surprised how often I hear that people think that the fabrics they pick out won't look as good as a pre-chosen kit, or that they're scared to do it themselves. This id designed to make you more confident, so you can make beautiful things!

Step 1: Inspiration is closer than you might think!
You're probably going to want to look for a larger chain type store for a few reasons (I like to hit up Walmart, Home Depot, and Lowes). The first main reason is you're not actually going to buy paint. The second reason is not only are you not going to buy paint, but you're going to take color cards and you want a wide selection.
The first photo attached is probably what you're NOT looking for which is a pure color gradient. Unfortunately, there's not much difference in trying to choose from this selection than there is in walking into your local fabric store and choosing blindly from a color wall.
The second photo is the type of paint display you're looking for (this one is from my local WaltMart). Notice that there are lots of pre-coordinated room painting suggestions!
