I only use metal bowls so thats probably out the question for me (assuming you would probably do ceramic type bowls).

I would be intersted in the treat jar IF it has a nice seal on it (most don't which is why I stick to rubbermaid type containers) and is large (having 3 dogs I need a large treat jar, another reason I usually use rubbermaid containers).

I make picture frames already so I myself wouldn't be interested.

Sorry if "I" am not too much help for you. But if I were speaking for the general public I'd say they are all great ideas!
