Hi Linmid,
You can do a search from the top right corner of this site (it looks like a blank square) put round robin row and you'll find all kinds of hits. You can also just google to get some idea. I can't make up my mind for a theme either, I am thinking either Mexican or flowe power.
Qbee also said that the group we are assigned to (5 peeps) could decide on the attach rows or not. I know I would got with the instructions I receive from the owner.
