When it comes to cooking or decorating, arranging in layers is a common technique. However, sometimes you want to mix things up and use different words to describe the same action. One synonym for "arrange in layers" is "stack," which implies a more structured organization. Another option is "layer" itself, but using different adjectives to describe it, such as "intersperse" or "alternate," can add more variety to the description. "Laminate" is a more technical term that refers to layering materials such as paper or plastic. Finally, "tier" is a great word to use when arranging in layers that rise upwards, like a wedding cake or a fountain.
