The big empty wall in the living room has been tough. We have LOT of pattern going on already in the curtains, the TV "hider" and the art already in the house.
We also wanted a HUGE piece. After searching on etsy and ebay I found a couple pieces I liked - but they were expensive. Like way more than I wanted to spend.
I decided to diy some art. After a suggestion on apartmenttherapy.com, I printed a 40% off coupon for Michael's and bought a huge canvas (price with coupon: $60 bucks). I didn't know the supplies I would need - the internets were amazingly unhelpful when I didn't know the right search terms, so I posted on facebook for help and found out I would need modeling or molding paste.
Michaels had some and little tubs were 14 bucks each (ouch).
I bout two tubs and a bunch of white paint assuming I mixed them together, but when I got home I realized that you were supposed to paint over the modeling paste. My two little tubs got me about a 1/4 of the way across the canvas...
so I had to make another trip (to another store - long story) for another brand of modeling paste...but it worked out okay. Not perfect, because the two brands are two different colors. At some point, I'll paint it all white, but for now it works!
(needs to be hung a little higher and straighter, but that is the only place its safe from the munchkin while it dries :)
