The wire is from Ikea and cost like $7-- cheap! Kevin installed it for me and the hooks for it are also from Ikea. I also wanted to have a decal to put over the line and this one seemed to fit great for what my vision was. I think I ordered it from wallquotes.com but can't really remember. I had a hard time putting it up and really getting the letters to stick and be smooth. I also put it up crooked. Luckily it was easy to re-position. The end product turned out great. Now two of the girls love to hang their recent art work on the "art line" and proudly display what they have created.
No mess all over my windows and everybody can see it. Now, take a trip to Ikea and make one for yourself! I've also seen people use the 1/2" curtain rods to hang the work too.
