I hope this is what Carolyn intended with this topic.
I used Carolyn's spider web tutorial and created the web.
I used tiled clones to create a set of them
I drew a circle on the tiled clones and did object clip
Viola, a nice patterned medallion.
Then I took the clone and imported it to ecal.
Created the polygon over the tiles and did a front minus back
changed the colors
I think I like this better
