To spruce it up just a bit, I decided to try a coffee stained picture frame. I figured this would be the perfect project for it. Here's what I did to turn an ordinary craft frame into the frame you see in the picture above.
 I bought an 8x10 frame and mat at AC Moore.
 I went home to prepare my stain. What you'll need to make a coffee stain is:
1/4 cup used coffee grounds
about 1/2 cup vinegar
Put the ingredients into a jar with a small piece of steel wool, shake it up, and let it sit for 24 hours. I initially used too much vinegar and my stain was weak so I ended up dumping some out and letting it sit longer.
 When my stain was ready, I grabbed a pair of rubber gloves, took my frame somewhere I could make a mess (our back patio), and rubbed the stain onto the frame with the steel wool.
After one coat when I realized my stain wasn't "strong" enough...
After 4 coats...
Do as many coats as it takes for your frame to become the color you wish (letting your frame dry completely in between coats). I ended up doing 4 coats. When it was all dry, I brushed off any loose coffee grounds and put my picture in it.
As far as stains go, this is a pretty thrifty option for turning an ordinary frame into something that looks more custom. The loose coffee grounds give it a slight rustic look making a new frame look loved.
Happy staining :)
