Isn’t this a cool idea? Even though I had the blog link (on the top left corner of the picture) I couldn’t find the actual tutorial. So I’m improvising. The easiest way I could think of doing this is with a paintbrush (of course) and glue. Modge podge or super glue work well. I suggest using gloves if using super glue. All you need to do is soak the brush bristles in glue, whichever it may be. Curve the bristles upward. Hold it tight until they stay that way. Let it dry. You can stick wire in between the brushes if you would like to give it a better grip. This method works but you can only hang lighter objects on it. Light coats, keys, etc.
Paint the brush handle for a cuter design! Or wrap it in patterned or colored duct tape.
