Here are some pics from our Creative Arts Walk we had last night. We did a couple Art in Bloom pieces that went in a local photographers studio as well as some tablescapes in our own shop. (note that the art in bloom photo with the vase goes with the art on the floor, not the photo on the wall!)
Thom-
The dishes used in the design are from TAG www.tagltd.com The herb plates on the table are from Sullivans www.sullivangift.com The piece you are referencing was done by Mary, my manager at that location. I did the two Art in Bloom pieces.
I found a plastic rectangular tray with very low sides (I think I got it at an auto parts store) and just cut oasis in slabs about 1.5" high. I did my design and then covered the edges with sheet moss. It was a very fun piece to do. It helps that I LOVE the stained glass that inspired it!
