Apothecary jar inspiration. Sure, this is great for Christmastime - what about sand & shells in the Summer... Corn & mini pumpkins, pinecones in the Autumn. Hmmm - what for spring? Nests & (fake) eggs? Jellybeans?
Glue clear marbles on the bottom of the items to raise them off the bottom of jar or lid (depending on if right side up or upside down) then add enough fake snow to cover marble. Bluish glass would be perfect. LA SOURCE
