Ideas for a fish theme kitchen?

I wouldn't do the fish netting. It's a kitchen. When that stuff get's a little humid or greasy, it is going to have dust pulling to it like a magnet and will look gross in no time.

If you MUST do a fish theme...do fish with a kitchen theme. Like find fish shaped jello molds or something to hang on your wall. Or it will look hokey.

Use a fish net with some colorful tackle hanging from it and a glass fish mobile (or make your own from more tackle) for a window dressing. Decorate the table with a gold fish bowl with a real gold fish. Hang an old fishing oar above the cabinets or a fishing pole--maybe bamboo. An old fisherman's basket hanging on the wall would be good for a mail catchall or put flowers in it. Store spices in a metal tackle box near the stove.

i would get 4 plain fish photos on a white background and take out all the color to make them black n white. then i would enlarge them and frame them

if you want to be a little fancy then put a soft color (example powder blue) to lay over the black n white, so instead of black n white it becomes black n powder blue. that might look really great in frames

you can also add whimsy to the room simply by picking more whimsical images. serious real photos will give it a serious feel

get fishing net

sailboats

old fishing pole

old lanterns

anchor

I think you can buy fish knobs. Consider wall art.
