I build all our nappies up ready to go once they are dry.
Means I can just grab one when I need to.
Wrestling a wriggling toddler & dirty nappy is bad enough without having to build the nappy too
Our changing unit is ontop of a chest of drawers
1st drawer : wipes, pockets & Ai2's
2nd drawer: fitteds
3rd drawer: liners, wraps, boosters, wet bags. (all organised into drawer dividers from ikea)
