I made a storage box for pendants: Took one of the big necklace boxes, took out the velvet-covered card lining, removed the two tags the necklace hooks onto, then folded the card edges the other way and pushed it back into the big box, so it sits on the bottom. Then I took the pendant boxes, cut off both flaps, and put the boxes side by side in the big box - you can fit about six or eight in. The pendants then sit one to a box, altogether so you can see them and choose easily which one to wear...
Also made a ring box - took out the velvet sponge pads from the little boxes, and fitted several together in another big necklace box - you can also slot rings between the pads...(someone else had this idea on here a while ago...)
Have got a pic somewhere - will post if this isn't clear!
