I just started working on a daffodil card. So far I have the beginnings of a plain paper model, and I pulled some papers to think about for the color palette. The pop up mechanisms are similar to the one used for my Easter egg card. For the smaller flower the mechanism is exactly the same, only upside down. (The open part faces out on the flower, on the Easter egg it faced the card.) The larger flower differs in that the pop up part is open both facing the card and facing out.
