The thing with my son is that once he starts making something he won't stop. After the button flowers, he wanted more flowers. So I broke out my paper craft books.
We upgraded from pipe cleaners and scrap paper to proper floral wire and crepe paper. He cut and glued, and I assembled. We did the roses sort of like they did here, but much lazier, just drawing everything free hand.
The iris is from one of my old craft magazines. Now he's insisting he needs more than one purple flower.
