I'm building my first modular, the Pet Shop, and have just run across flower petal pieces that are basically fluted 1x1 round plates. Am I just daft or are these new? I wasn't able to find them on Bricklink but I'm no BL savant.
This brings to mind a question. How many new elements, on average, does TLG introduce each year? And do they in turn have to retire a certain amount each year?
