As per a request, I've done a layout with butterflies on an 8 1/2"x11" format. I also have a couple of samples of butterflies done using some of the filters in Inkscape .48 and the Clip feature in the Object drop-down menu. They make it easy to create a variety of custom designs to suit your needs with the filter options. For those using the Print and Cut techniques, it's great for that too! If you want the svg and png files it's here.
