Sweet and chocolate bouquets: chosen for one person, opened in front of everyone
A box of chocolates is private. The same chocolates on skewers, wrapped as a bouquet, are not: they are handed over while other people watch and taken apart while those same people help themselves.
That difference decides most of the choices around this format.
The contents are a guess about somebody
With cut flowers you can be vague and still be right. Here you are choosing what another adult will put in their mouth, in public, with an audience waiting to see whether they enjoy it. Nut fillings, dairy, alcohol centres, sugar avoided on medical advice or on principle, a child too small for hard sweets: any one of those turns a generous object into something the recipient has to be polite about. Politeness then hides the problem completely. You go home thinking it went well.
So ask, or ask somebody who would know.
Where the person really is unknown to you, plain wrapped chocolate and boiled sweets make the safer body of the arrangement. Anything unusual goes in the outer row, where it can be passed on to somebody else.
What a careful build looks like
Every sweet keeps its own factory wrapper and is fixed to a wooden skewer through that wrapper, never through the sweet itself. The skewers are gathered in a spiral and trimmed to one length, so the bundle stands on a table without being propped. A collar of paper, mesh or felt closes the outside, and the gaps between rows are filled with something nobody is meant to eat.
Pull one skewer out and the rest should stay where they are. If half the front row comes away with it, or the item is glued into the collar, the arrangement was made to be photographed rather than eaten.
The other thing to weigh, literally, is the ratio of sweets to filler. Filler is cheap and volume is impressive, so a large silhouette can hold surprisingly little, and the heft in your hand tells you more than the diameter does. Ask what is under the collar before you order.
Heat, and the season you are ordering in
Chocolate is the one ingredient with an opinion about the room it stands in. Warmth softens it and creases the wrapper, and as it cools again the fat rises to the surface as a pale bloom that reads as spoiled even when the sweet is perfectly good. Keep the arrangement off windowsills and away from radiators. Have it carried upright.
In warm months a firmer sweet makes a better body for the bouquet, with chocolate kept to the top rows where it can be eaten first.
The moment it is handed over
Nobody stands one of these in a corner. It goes on the table, it is dismantled, and the person who received it does the giving out. That is a pleasant thing to hand somebody on a birthday in an office or a classroom.
Sweet and chocolate bouquets are also the version of the format that children understand instantly. A vegetable arrangement needs a sentence of explanation first.
If the person you are sending to in Yerevan lives alone and does not eat much sugar, another format will land better.
