What You'll Need:
-old rug/boring rug
-a great paint color to match your decor
-fabric paint medium- found at any craft store
-a stencil of your pattern
-masking tape/blue tape/ frog tape
-cheap foam paint brush
Here's What to Do:
1) make sure your rug is clean and vacumed!2) create a stencil out of cardboard or buy one in a pattern you like. I made a stencil/cardboard pattern and used it to get my tape lines straight because i didn't have a piece of cardboard big enough too fit the width of my rug.
3) Once your rug is all taped up (or you have a fancy stencil, like these ladies) use your foam brush to carefully sponge and paint your rug. Be careful not to get any paint under your tape (this is especially hard to do with a stencil, tape is a bit easier to get a clean line but it is more time consuming).
4) Let the paint dry completely. Peel it away and enjoy!
If your painted lines are too "pokey" you can gently take a sander to it. See here.
I love how my "new" rug makes my apartment look and feel a bit more complete :) And i did it for under $6! Whoot whoot!
