If I were starting from scratch, my plan would be:
Sheets: One set per bed, and one spare set for each bed size, all in neutral colors so that it doesn't matter what room they go into.
I like the previously-mentioned idea of a spare flat set that would work for any bed size, but I can't rely on myself to get the sheets washed and dried in the same day that I take them off, and I hate using a flat sheet as the bottom sheet.
Towels: Four large towels per bathroom - one as a hand towel, one as a bath towel, and two spares to be in the laundry or for guests or if someone just got one sopping wet. (Family shares bath and hand towels; guests would get their own.) Six washcloths per bathroom. (Family doesn't share washcloths.) All in white.

I have trouble keeping track of everything lately.
