I had to show you this example by "emil" in the gallery even though I had to edit it wonky. I love Roy Lichtenstein's work.
But how cool (and cheap) would it be to make a super large family photo? Mount it to some MDF or Masonite with Mod Podge and you've got a statement piece. Or your kids favorite superhero or teen star? Just watch for copyright infringement issues.
I've used the rasterbator (blush) site to convert small pictures into large pattern pieces for applique wall hangings. I've then taped the pattern to a large window so I can see through the papers and then traced the pattern onto fusible web.
Have you used these before? Do tell!
