Successful Sunprints!

Today was a successful sunprinting day. The weather was absolutely gorgeous with very little wind. And.........I had gone shopping for some great items to use on my sunprints. After the three I did the other day (that I posted here: http://www.flickr.com/photos/stegart/), I learned what types of items are more successful and which to avoid. Brass stencils, sequins, and washers work great! Now I need to work on making a nicer green from blue and yellow. I'm actually using a golden yellow, is that my problem?
