How about a fresh apple or pear? I keep seeing them popping up here and there. These are some of my Etsy finds:
Set of 3 ceramic Pears from Element Clay Studio, Vintage Candy Apple Dish from Rosy Apple Vintage, Cedar Apple from Holzfurhaus, Large vintage brass pear lidded container from High Street Market
A Pair of crocheted Pears from Seventytwostitches, Apple Brooch from Naomi Murrell, Pear, Apple Salt and Pepper from Sweetshorn Vintage, Print 2 half of a pear from Big Girls Don't Cry
And by the way, I'm sure you have seen some pear terrariums lately, I like the one in the Brick House.
