Article has been replaced with another with a complete list of motifs, not just the racial ones: ESO Motifs
There are many exotic crafting styles that represent the culture and prowess of the various races of Tamriel. Each style provides a distinct appearance to an item and within a style there are several appearance substyles for various levels.
Summary
There are currently 20 crafting styles. A crafter will automatically know their racial style and can learn others by using motif books / scrolls found around Tamriel. The styles are: Altmer, Argonian, Bosmer, Breton, Dunmer, Khajit, Nord, Orc, Redguard, Dwemer, , Ancient Elf, Barbaric, Daedric, Imperial, and Primative. The motif books are found in standard containers (backpacks, cabinets, chests, dressers, nightstands, trunks, urns, and vases). The standard motifs (blue – character races) are found in non-veteran rank areas and the rarer ones in veteran regions. Some of the rarer ones can be found in areas where the main questline, guild questlines (mages’ guild, fighters’ guild), and added content (Imperial City, Orsium, etc.) take place.
