My son's entire bedroom theme came from the fact that I saw some car fabric at the store and thought it would make a cute blanket. I tied him a quick blanket for Christmas using this fabric (I think it's Debbie Mumm).
Once he moved to a "big-boy" bed, we used the blanket as a bedspread. The car theme propelled from there.
I scanned in a piece of the fabric into my computer and blew up three of my favorite vehicles to the desired size.
I cut pieces out of felt to create cars/trucks that looked similar to the ones in the fabric. I stretched some white fabric over cardboard and glued the felt pieces onto it. I framed it and ended up with this.I actually made this over a year ago. I was worried that the felt would fade, but it still looks great. It was a cheap way to make wall art that matched the theme perfectly. I also like that it has some texture to it.
