I've been folding hearts, using the directions from this blog. I hope the picture is clear, I used my scanner. (The darn camera is out of batteries, again.)
The picture is very close to actual size. I'm getting 2 hearts to each piece of paper.

I'm using the origami paper from my half-price calendar. Fortunately, the paper so far has been red and pink.
