I saw this metal 12" tray at Hobby Lobby and it looked like it needed a Hallingdal design. The design includes many different kinds of Hallingdal flowers in their favorite colors. I used Jo Sonja products. If you don't find the tray, any round surface is wonderful. The design measures 11 inches, but the design you will receive is at 90%. (Note: The blue in the photo is brighter than the original.)
