This completely depends on your preference, but as a rule of thumb we would use the following:
- Coat hooks: for lightweight items of clothing like jackets and coats.
- Hat & coat hooks: for multiple jackets, hats, and items of clothing.
- Robe hooks: for lightweight items of clothing like dress robes.
- Cabin hooks: to hold open exterior doors and gates.
- Cup hooks: for displaying items like mugs, pans, and utensils.
