How to make a light box when you need one in a hurry.

I decided I needed to try the triangle block that Victoria over at http://www.15minutesplay.com/ posted. It took a little more than 15 minutes but it was fun to try a challenge.  My points are way off but for a first time I think it looks ok.

To make the paper patterns to sew the fabric on , I traced the pdf that I printed.  My printer stopped working for some reason and I only had one copy so I had to trace them.  I do not have a light box but I have a sewing machine table that has a clear inset for my machine.  Here is how I 'made' my light box.  It worked great.  I guess out of necessity comes invention..
