Congratulations Dennis i hope it all works out for you.
Some input if you dont mind.
A key point for merchants is the space a product takes up versus its value in sales.
A metric stores keep a close eye on is $/sqft of sales. In order for that to be as high as possible yet affordable to their target demographic they watch how this works out in the merchandising of the product.
While your stand looks fine in my view it means unless the ornament is merely hooked on then someone wanting the 3rd one along when the row on each arm is full will have to lift off the first 2. This is a potential opportunity for damage to the goods or dropping and causing even more damage.
While hooks will solve the problem hooks get lost and so the loop for hanging it will inevitably be used.
My suggestion is to think in terms of making a tree with many more shorter branches and sub branches like the veins in a leaf.
Then consider putting a lazy susan under the stand base to enable it to rotate but put something in between the base and the lazy susan to make it slow to rotate. For that matter you might just try wood on wood with a dowel.
The more customer and merchant friendly you make your display stand the more he will like you and your product and the better it will sell your products.
In addition if you make a dedicated little peg for each ornament then he can also see at a glance when his stock is out and how many and reorder without having to do much work. It also helps for theft monitoring. Many smaller retailers will keep positions fully stocked with stock from the storeroom to aid in this matter. At a glance one can spot if one is missing when someone has entered the store.
Hope some of these aspects help. Also consider adding a little plaque to the top like a tree top and putting a brand on it with a small punchline about the product being hand made with loving care in the USA etc something like that adds to inlfuencing the sale for the consumer looking at the tree. Small little things in the mechandising can make a huge difference. Simply saying give a gift that will be remembered every Christmas will help someone spotting it think what and prompt the "thats a great idea" flag in their head.
Best of luck
Oh Dennis and consider the same sort of thing to display your bowls. Think of a stand that will offset and stair case them so they are not all on one plane. This will allow him toget the density up too and create a higher display than flat or on a shelf next to each other. It makes them a display piece.
