Here is a great cost saving idea for you artists out there.....Shop thrift stores and look for canvas art that is for sale for mere dollars. Trust me, most are going to be UGLY art but you are not buying it for the art!
Paint over what was on there and create your own art. I actually took some plaster and crackle and created this over the top of a really dated looking canvas that had been wrapped with some weird fabric. Instead of trying to get the fabric off, I just went right over the top with some black paint, then the plaster and then my birds on a wire. I think I paid $4 for it and sold it for $40.
