AMSI was started in the early 1950's by two professional model builders, Lila and Virginia who lived in San Francisco. They found it impossible to locate the true to nature colors they needed and decided to begin to make them for their own use in model building. Soon, their true to life colors of ground foam and miniature landscaping supplies became a successfull business of its own and AMSI, formerly Architectural Model Supplies Inc., was launched.

Ground Foam

AMSI makes our basic foam in three grades: Fine, Medium and Coarse. When ordering a color, use 1 for Fine, 2 for Medium and 3 for Coarse. Click Here for more information.
