I have been wanting to try this and finally took the plunge.
I used the largest Nesties, so this is about 4.25 across.
The white layer is the one that opens - the pink scallop is just an extra backing. I do not have much pink - I used a scrap of DP, and some mauve metallic for the middle scalloped layer.
Lace is from Pizzazz Aplenty, as are the half pearls - both cranberry. Petaloo glittery flowers, and CB heart die cuts.
