In 2012 the Sante Fe Morgan mold was added to the Design A Horse (DAH) program; a program of models and colors that a collector could personalize. Most of the molds were available, and special colors along with mold customizations would be released as limited specials at various events and special occasions. There are no known quantities as this is an 'open run' production. The standard colors include: black, brown, bay, white, buckskin, chestnut, palomino, and sorrel. There is an appaloosa pattern, an overo pattern, and a tobiano pattern. There are also a variety of face and sock markings, along with buyer's choice of matte or glossy finish.
"These are not custom orders, nor are they One of a Kinds; These are a line of models that you can have personalized your way. Models may be marked as "My Stone Horse 2009". They are not limited editions as anyone can order any pattern that is offered here in any combination." Stone Company. Models after 2009 had a hand written 'DAH' along with year made. 2010-2012 didn't always have that mark, but starting in 2013, it became a standard signature.
Also available as a gelding - PM109G, and as a mare - PM109M. 2024/2025 Base Cost of $290.
