When I got home, I used a corner punch to round the corners of the card stock sheets. This was surprisingly time consuming work. The Martha Stewart punch I used could only handle two sheets of card stock at a time. I had 200 sheets of card stock and four corners on each sheet, so I had 400 punches to make (it actually took more than that because I didn't discover the punch could take two sheets until I was a good bit into the stack of paper).
I contemplated painting the edges or running marker around them, but that should have been done before they were put together. What's more, when I tested using a marker on the edges, the paper soaked up the ink unevenly and the result wasn't very nice looking.
If I was doing this project six months ago, the perfectionist in me would have scrapped everything and started over. I am giving myself permission to use the fans as they are. I hope people can focus on the illustration and program content instead of the edges.
Did you have to settle for less than perfect results on a project you tackled during wedding planning?
