Here are some powerpoint slides/backgrounds for Epiphany 3C, which feature boats and fish/nets.  The images I used for creating these slides are from Hermanolean Clipart.  This site allows the use of its material for nonprofit purposes and features both color and black and white images suitable for bulletin covers and slides.  As always, click on the pics to go to my flickr account to view and/or download larger versions of each (800×600 px).  Although it is hard to see this with the white background slides, they too are 800×600 in size.
