Patternbank is a large company who sell seamless patterns, mine too. They have nice mock ups, like this dress. The motif is a flower bouquet in a pot with geometric patterns.
This page includes a sketch I made pulled over on the road near Pontiac, IL, a shield I stamped using a stamp I carved (pretty crude , but still works!), and some stickers I had made of sketches of other things in the area.
