Tired of looking at your dreary backyard? James DeSantis, Garrett Magee and Melissa Brassier are the team behind Bravo's latest hit show "Backyard Envy," and they have a super easy project that will take your outdoor space from drab to fab.

A beautiful DIY garden mirror — on a budget! (These things can go for hundreds of dollars.)

"We treat interior walls the same as exterior walls," James says, "so we really want the exterior to a reflection of your interior."

First, find an old window at an antique shop, flea market or used furniture store. Have the glass removed by a professional and replace them with custom-cut mirrors. (You can get them cut at any glass shop for about $3 a piece, our pros tell us.)

Then, apply a simple hardware store caulk to the edges of the mirror and place each piece of glass onto the frame. It will take 24 hours for it to cure. (You can use clamps to hold it down!) Finally, use two simple screws and a heavy-duty picture wire to hang it either on a fence or concrete wall.

"It adds character [and] depth," James says. (It sure does!)
