Seems like foods are pretty easy to replicate, but here are some things from my wishlist:
All types of WOOD (cedar, pine, palo santo, oud, mahogany, sandalwood, juniper, cypress, teak, walnut, oak etc)
All HERBS (clove, basil, thyme, pepper, bay leaf, rosemary, lavender, cardamom)
Real LEATHER (not like mens cologne!)
The scent of a leaf from of a TOMATO PLANT would be incredible
RAIN (petrichor)
Terra Cotta pot / CLAY
CITRUSY (bergamot, ginger, lemongrass, grapefruit)
NEROLI (the closer to a real orange grove the better)
FLORAL (peony, jasmine, lotus, gardenia, geranium, honeysuckle)
DANDELION (like your fingers smell after picking one)
HAY (like stacked in a barn)
ART SUPPLIES A new box of crayons, pencil shavings, play dough, paper or finger-paints
Dry LEAVES off of a forest floor (not like BBW leaves)
