Several of us are doing the flower BOM here on the board. I was thinking I might like to have more than 12 blocks when I'm done so I started hunting around the net. This site has several state flower blocks. The ones posted in 2009 will vanish 1/31/10, but more are scheduled to be posted. If you are interested in more flower, you might want to give it a look.
