The rapid success of his business soon required him to move the shop to larger quarters.  He occupied a series of addresses on Cahuenga and Selma Avenues, and hired many skilled leatherworkers and silversmiths to augment his own skills and vision

Tom Mix, his first great customer and friend in Hollywood, was joined by many other film stars, who assured Eddie of a built-in clientele.  This connection with the studios quickly brought him the job of supplying the Egyptian-style chariot harnesses for Cecil B. DeMille’s “The Ten Commandments,” in 1923, and twenty Roman-style chariot harnesses for MGM’s 1925 production of “Ben Hur.”  Another early studio job was supplying two hundred buckskin suits for Universal’s 1923 movie “The Days of Daniel Boone.”  This order alone came to more than four thousand dollars, a huge sum in those days.

Bohlin’s relationship with Tom Mix coincided with the beginning of the era of the super fancy movie cowboy, and his skills were matched by Hollywood’s demands for spectacular goods in the Western style.  In addition to the early custom work he made for Tom Mix, he produced a richly mounted custom saddle, bridle and breast collar for Buck Jones, and a pair of pistols inlaid with gold and silver for William S. Hart. 

Soon, every successful Western star had to have Bohlin equipment for personal appearances, parades and the movies themselves.  Eddie’s movie cowboy customers over the next thirty years would include Ray “Crash” Corrigan, Ken Maynard, Rex Bell, Will Rogers, Leo Carillo, Monte Montana, Monte Hale, Gene Autry, Charles Starrett, William Boyd (Hopalong Cassidy), Roy Rogers, Dale Evans, Clayton Moore (the Lone Ranger), and Ronald Reagan. 

Other prominent customers in the Los Angeles area included the P.K. Wrigley family and the banker Marco Hellman, who was Grand Marshall of the Rose Parade in 1929.  More distant customers among the rich or famous included Lyndon B. Johnson, the Specht family, the Maharaja of Jahore, the royal family of Saudi Arabia and the King of Kuwait.
