I revealed my demo swap yesterday and as promised (as long as Blogger does his or her thing) here's a quick tutorial on how you can make your own.
Score a piece of 3-3/4" x 11-1/4" card stock at 3-3/4" increments i.e. 3-3/4" & 7-1/2"
Fold one piece under & stamp on the front of the card, punch out a half circle with a 1-1/4" circle punch. This picture shows how if you clear emboss the inked image it is much brighter (LHS) - I just went with plain stamping on my cards for convention (as per the RHS) - gotta to think about your sanity.
Turn over & use a thin strip of adhesive or glue to stick one of the outer thirds to the strip. In the example below you'd bring the left hand outer corner into the glue strip.
Glue the 2 wings & viola done - now how easy is that.
And the finished project again:
