Those are very cute knobs and pulls.
I think they will have the best impact if you select to use them in just one cabinet or area.
They might be well suited to the glass door "curio" cabinet facing the dining room.
Or, perhaps on the two drawers flanking the sink.

I agree with francoise : ) Limiting them to one area - They are adorable though!!

How sweet!
I like the fact they're different.

I agree with special places.
Do they make a plain knob to compliment these?

What I think would look great is to use the pulls and then a knob that is plain but the same in color and texture. That way the pulls would command more importance. Those are just so great, I love them! The other images on the knobs are a little too childlike for me.

I don't know. I've seen a bunch of kitchens around here (beach area, FL) with these knobs and while I theoretically agree with what people are saying about accents, I have to say that IRL they always look to me like, "Ooh, someone gave us a couple of these cute knobs and we wanted to use them somewhere," rather than like it was planned, so I'm not so sure that's the best advice on how to use them.

Thanks Everyone for your feedback and suggestions... I also purchased a plainer knob with my "samples", because I was pretty sure having "cute" knobs everywhere would look too busy and actually detract. Here is the plainer knob I got.

I like that it has the darker pewter color like what's in the beach knobs, but wonder if we should pick one that is more simple?

Also... The beach pull is only 4" across (3" holes).

Will this size be large enough for trash pullout doors under the sink? How do you know what size looks in proper scale with the doors? Maybe I should just wait until the cabinets are in...but I think I need to tell cabinet maker whether I want a center hole for a knob or 2 holes for pulls. Maybe simpler pulls or knobs on the lower beadboard drawers/cabinet doors and a few beachy ones on the plainer uppers?

Definitely like idea of using a beach knob on the small, angled glass doors at the entrace to the kitchen, but I'm still having trouble visualizing the rest!

Just my opinion, but I don't think having a mixture of the cute knobs everywhere would be too much. I imagine from far away the knobs won't look overwhelming because they are shaped like standard knobs with the accent on front. Personally, I would probably at least use the knobs on all of the upper cabinets. They're very cute and I love the idea of using a mixture of all of them.

It's too much when YOU feel it's too much and not a knob before. You love them, so enough is going to be somewhat more than less. You'll just have to experiment a bit. Have fun! They seem to need names, BTW.
