Paper Imagery has these incredible collage sheets and the yahoo group PIDSwaps has ATC swaps each month for a different collage sheet. Here is the link to the Paper Imagery yahoo group.
I have to tell ya.... the collage sheets are so incredibly detailed, beautiful and printed on gorgeous cardstock it's almost blasphemous to do anything but display the image on the collage sheet. Are you feelin' me here? I really had nothing to do here except glue, add some distress ink around the edges and a flower. The rest. From Paper Imagery. The quality is incredible.
