I'm not a pro. What do you really love that you feel needs to be displayed? Pick a few things that complement each other in color and style without being too matchy-matchy. Avoid overcrowding your items; you don't want a cluttered look.

The blue and white

Will remove the glass

Notice some of the items in this hutch to fill in and add height to each shelf.

Yes, do remove the glass as they are lost and offer no contrast to the dark background .Accent with white and add life with small greenery bits Remove dried flowers from basket- adda traditional lighted garland if you must.

How is this?

Better pic

Try grouping some items, and stagger where they sit on the shelf (front to back). For example, try grouping the candlesticks a bit closer together, and place one closer to the back of the hutch. Try placing the small plate overlapping the round plate. Same with the goblets - make them into a group with one sitting closer to the front of the shelf. And, same with the little dishes. Hope that makes sense...view the images above from DK and you'll get an idea of grouping/spacing.

Also - the cake plate gets lost. I think you need something white or blue/white on that shelf, too.

On the lower shelf, I would center the rectangular plate, and put larger round plate to the right. The pair of vases to the left, but closer together, less than a vase width apart. On the top shelf, the smaller round plate above the vases, the pair of footed vases in the centre (again, closer) and you need one more thing or grouping above the larger round plate. Let's see how that looks for a start.

Nice hutch.

Color and symmetry are with considering. Would limit clear glass items to only your most favorite item(s).

Your better pic is much better.

Love the hutch and entire room! Maybe add a few photos and books?

Better?

If you want the added height and interest - add more items to the top. The single basket of dried flowers looked forlorn - 1-dead flowers/ no life. 2-solitary basket needs a buddy

The tall round plate is too tall for the upper shelf. The smaller items should be grouped. It looks unbalanced.

All of your lovely plates are the same and offer very little contrast to make the grouping interesting.....adding say brilliant blue for example, to the mix along with classic pewter or zinc finish might give you a more classic feel while adding a bit more color and will allow you to add some art in similar colors......also your chandelier while pretty has nothing to relate to on the table...if you can change it out to black or silver or zinc and add a bowl dish or vase on the table with the same finish, ie.....cut crystal simple vase with flowers under the crystal chandelier it will look planned instead of displayed as in a furniture store.

If anyone remembers Candice Olsen and her design tv show, she explained once that anything you put in a room needs to relate to another thing in the room be they matching lamps or the same finish on a bookcase and a chair even though the chair and book case do not look anything alike except for the wood tone....does that make sense?

This room has the bold orange sofa table, but it relates to the curtains and the pictures, the brass relates to the mirrors, the wood legs relate to the coffee tables, and the yellow relates to the fireplace tiles, etc.

Also if you have only one red thing in a room it will shout out loud and clear but if you add a few more red things in the room, the red becomes less noticeable and outstanding.....things to think about in displays.

Beautiful house and dining room!
You have some beautiful pieces, you just need to add in some more pieces and then keep trying arrangements until you love it.
Some solid coloured white or solid blue pieces would be nice in the mix.
Those lemons would look nice displayed in a white bowl. You could also use the large rectangular platter set on the buffet surface to carry the blue/white china down, so not all pieces are in upper shelves.
Look around your house for some other items like pots of greenery, seagrass baskets, coordinating cloth napkins, tray with tea pot and mugs, or tray with pitcher and glasses, etc...
Lots of inspiration to be found in searches for hutch styling. Have fun with it. :)

This blog site has some good ideas. :)

Think about threes and not about soldiers, layers and not line-ups. You need more pieces if you want to make this your focal point. Are there grooves in the shelves for the plates to stand in? Consider buying a platter stand and putting the large platter, flanked by the two candlesticks, on the very top of the hutch. Are all of these pieces for Passover? If some are and some not, I would group the ones for Passover together. Do you have a silver tray? You could bring back the decanter and two highball or wine glasses and place them on it at the bottom. You'll probably need more pieces in the blue to flesh out the arrangement. Put in your request if anyone will be buying you a gift soon.
