First lay down the first flower (the yellow) and put glue only on the tips of the outer two petals. If you put glue on more than the tips, the flower does not open properly. Attach the next two flowers (green) as in picture one above. Next put glue, again only on the tip, of the inside green petals of the two green flowers. Place the next petal on top of both spots of glue in the center of the stack.(step 2 pic).
Put glue spots on the tip of the outside petals of the flower you just attached AND the petals next to them of the other flowers. (You will have four glue dots) Place two flowers, one over each set of glue spots as in picture three. Put three glue dots on the 3 center petals and put the last flower on top of all three spots of glue.
Let the glue dry thoroughly. Put a something heavy on top of the stack until dry. When It is dry it should open up to look like picture 4.
