Elephants have a way of multiplying. One is bought, one is given, one comes back from a holiday, and within a few years there is a shelf that looks less like a considered arrangement and more like a small gift shop.
The pieces are usually fine. The problem is grouping, and it follows a few reliable rules.
Why accumulation reads as clutter
An arrangement reads as deliberate when the eye can see a relationship between the objects. Accumulated objects have no relationship, because each arrived independently and none was chosen with reference to the others.
The eye registers that instantly. What you are correcting is not quantity but the absence of a visible decision.

Odd numbers and varied heights
Two of the oldest rules in display, and both hold up.
Odd numbers, particularly three, read as an arrangement while even numbers read as a pair or a row. Three pieces of clearly different heights create a triangle for the eye to travel around, which is why it looks composed.
Equal heights are the commonest mistake. Three elephants of the same size in a line is a row, and a row reads as storage. If your pieces are similar in size, raise one on a stack of books or a small block to create the variation artificially.
One surface, not five
The single most effective change available. Elephants distributed across a mantel, two shelves, a windowsill and a side table read as an infestation. The same pieces gathered onto one surface read as a collection someone assembled deliberately.
Choose the surface that suits them best and bring them all to it. The rooms that look most considered are usually the ones where similar objects are concentrated rather than scattered.

Leave space
Objects need air. A group with clear surface around it reads as chosen; the same group filling the shelf edge to edge reads as everything that would fit.
As a rough guide, leave at least a third of the surface clear. If that means removing a piece from the group, remove it and put it somewhere else in the house rather than squeezing.
Mix materials deliberately
A group of six carved wooden elephants in similar finishes is monotonous however well made each one is. Introducing something different in material, a brass piece, a ceramic bowl, a stack of books, a plant, gives the eye variation and stops the group reading as a set.
Our turquoise and gold and white and gold carved elephants work well together precisely because the finishes differ while the carving style matches, which is the balance to aim for.
Splitting a collection across rooms
If you have more pieces than one surface can hold gracefully, the answer is not a bigger shelf. It is distribution by room rather than by surface.
Three on the hallway console, one on a bedroom shelf as a solo piece, and the rest put away for now. A single elephant alone on a shelf reads as a deliberate object in a way that the eighth one in a group never will.
Rotating, which nobody does and everybody should
Objects stop being seen. A piece that has sat in the same position for three years is invisible to the people who live with it.
Boxing half a collection and swapping it twice a year costs nothing and makes both halves visible again. It is the single best argument for owning more pieces than you display.
Editing an existing group
If you already have too many, the method is simple and slightly ruthless. Take everything off the surface. Put back the best piece first. Then add only pieces that improve the arrangement, stopping the moment one does not.
You will usually stop at three or four, and the pieces left over are not failures. They are candidates for another room or the rotation.
Our guide to hanging an elephant head covers wall pieces, which follow different rules entirely.
Questions people ask
How many ornaments should I group together?
Three is the reliable number. Odd numbers read as an arrangement while even numbers read as a pair or a row, and three varied heights create a triangle for the eye to travel around.
Why does my shelf look cluttered?
Usually because the objects accumulated rather than being chosen together, so the eye cannot see a relationship between them. Concentrating them on one surface and leaving clear space fixes most of it.
Should ornaments be the same size?
No. Equal heights in a line read as storage. Vary the heights, raising one on books or a small block if the pieces are similar in size.
How much clear space should a group have?
At least a third of the surface. If achieving that means removing a piece, remove it and put it elsewhere rather than squeezing the group.
What do I do with pieces that do not fit the group?
Give them their own spot in another room, where a single object reads as deliberate, or box them and rotate the display twice a year so everything gets seen again.
