Guests are able to create customized stuffed animals featuring different licensed and original designs at each Build-A-Bear Workshop location, as of 2015. The process involves choosing an animal, such as a bear or bunny, then filling it with stuffing and a heart before adding accessories and clothing.
Build-A-Bear Workshop offers a stuffed animal creation process in addition to selling a variety of pre-made stuffed animals. Many of its custom-creation animals either feature a generic design that draws from different themes such as fantasy princesses and sports or from different movie and television properties such as "The Avengers," "Teenage Mutant Ninja Turtles" and "My Little Pony: Friendship Is Magic." In addition to bear animal bodies, the store also features designs that recreate other animal characters, such as turtles or ponies.
Customers are able to make a custom bear both in a physical store and online. The customization aspect largely focuses on the different accessories available to purchase. Many of the accessories are different clothing items, such as skirts or shirts, along with traditional accessories, such as hats, shoes and capes. Certain special lines also include custom accessories according to the source material. For example, the "Teenage Mutant Ninja Turtles" line includes stuffed version of each character's weapons, such as Michelangelo's nunchaku or Leonardo's katanas.
