The overall effect is supposed to give the general impression of flower shapes (it's not a literal floral print, obviously), as well as play on the contrast of textures. The more realistic flowers are crafted from masking tape and receipt paper, whereas the abstract flowers are various wooden and metal bobbles from the hardware store (well, technically, the hardware section of the ReStore). You could probably get most of these supplies at a dollar store as well, though!
