Making a Marquee Letter

 First we bought a 24 inch letter from Hobby Lobby for $14 and a set of out down lights from Target for $25.  We them drilled holes in the wood to fit the lights.  And glued an L shaped trim, called corner trim, all around the letter to hide the wire from the lights.

You can see the L shape of the trim

 Then it was all spray painted blue.

 Then we placed the lights and wrapped the wire inside of the back of the letter to hide them

 All Done!
