I designed these repeating designs with the thought that I might use them to have a custom wedding band made for myself, but in the end I didn't use them. However, I liked the design, so I put them together into one image and decided to share them here. I used the motif of a mallorn leaf (based on the Peter Jackson film version), and took other inspiration from period medieval designs. I want to try to clean up the file a little for the future, but this will have to do for now, as I don't have access to a decent photo editor at the moment.
If anyone would like to use these, I would like to submit them as stock images. I only request that you credit me for the design, and that you please put a link up here in the comments to what you have done with it.
