*Intro to Sash Making* is a field book from Steve Quillian’s five-day Intro to Sash Making workshop in Lutz, Florida. It follows the real arc of the class as students move from rough lumber to finished sash, learning the principles, sequences, and shop judgment behind traditional window craft. This book is not simply a manual of measurements and tool settings. It is a record of what happens when joinery, machines, layout, mistakes, repetition, and human formation all meet in the same room. Readers follow the workshop through morning millwork, the trinity of the shop, reference faces, mortise-and-tenon joinery, storm windows, casement sash, the Sash Factory sequence, double-hung construction, meeting rails, divided lights, material yield, team workflow, and the beautiful exhaustion of Brain Fry Friday. Written in a direct, reflective, shop-tested voice, this book is for artisans, contractors, homeowners, preservationists, students, and anyone who wants to understand why sash making is one of the clearest gateways into the whole world of Window Craft. It shows how beginners move from thinking in pieces to thinking in sequences, and how the work itself teaches patience, accuracy, order, judgment, and service. More than a technical book, *Intro to Sash Making* is an invitation into the Artisan Way: master a movement, master a sequence of movements, master sequencing your sequences, and teach another to master a movement.
