The smell of hot cotton towels, fresh from the dryer, as I fold them.
Just purchased a single complete set of towels to outfit all five bathrooms of the house at one time. By my accounting this means 6 bath towels, and at least 5 hand towels and wash cloths. Luckily there is Ikea: $90 including a couple spare hand towels (which in my experience are the ones which A) get dirty fastest, and B) are rather likely to get permanently stained.)
So the first step after buying them was washing, drying, folding, and now they will be put away until I need the house in guest-presentable fashion.
