Decorations are fancy embellishments of your goods that, while unnecessary, greatly adds to their value for trade and other purposes by adding another material to the base item. Most decorations have quality levels: a base value of 10☼, multiplied by its material multiplier and quality multiplier, separate from the item itself. When an item is decorated, it is shown with double angle brackets - for example, a (no quality) decorated +steel battle axe+ becomes a «+steel battle axe+». Decoration quality is shown outside the double angle-brackets, the item quality remains within them with the item. So if you have *«+steel battle axe+»*, you have a +steel battle axe+ with *decorations* on it. When an item has more than one decoration the quality level of the best one is shown.
There are a number of caveats to these embellishments. Weapon decorations do not affect combat multipliers, even if your maul "menaces with spikes of steel." Adding decorations to an item does not increase its weight; this may be a bug. You cannot stud a metal object with the type of metal it is made out of. Decorations on "grey" items (with brackets) that were gained in battle, stolen from or traded with a caravan, certify the product as "home-made" (brown), and make it count for your exports.
You cannot specify a specific object for a dwarf to decorate; their pathing will cause them to use the closest suitable object (yes, that will always be a barrel). With the addition of linked stockpiles, it is possible to set up a stockpile that will lend its contents to beautification; this sounds easy and nifty but isn't; it's a pain to set up and keep track of. In the past, locking all the desired content up, including the workshop and misbehaving dwarf, was the way to go. This still works.
 Types of decoration
- Bone, Hoof, Ivory or tooth, Pearl, Shell,
- At a craftsdwarf's workshop, objects can be decorated with bone, hoof, ivory or tooth, pearl, and shell. Requires bone carving. You cannot choose what kind of object to decorate. Decorating with bone uses up a whole stack of bones. Bug:2011

- Metal studs
- At a metalsmith's forge, objects can be studded with various metals. Requires metalcrafting, but does not require fuel.
- At a clothier's shop, cloth images (plant fiber, silk and yarn) can be sewn onto clothing items (including leather armor) and bags. Requires clothesmaking.
- At a leather works, leather images can be sewn onto clothing items in the same manner as cloth, with the same restrictions. Requires leatherworking.
