| Know before using | Public pages explain the organization and calendar, while many classes, meetings, programs, and benefits require registration, payment, or membership. CGOA's statement that it sets a national standard is its own mission language, not evidence that every class, member, chapter, instructor, or portfolio is independently accredited, approved, or suitable for a particular learner. | Patternmaking knowledge, controlled measurement files, production conventions, and sewn fit testing are still required. The software does not validate body measurements, ease, balance, grading rules, fabric behavior, construction, or product fit. The project currently labels its user wiki manual as needing updates, so confirm current commands and file behavior against the installed release and active support channels. |

| What the source establishes | CGOA's current public pages identify it as a volunteer-led nonprofit and describe online education, in-person and online events, local chapters, mentorship, scholarships, professional programming, and portfolio-based Masters skill-building programs. Its calendar distinguishes specific classes, meetings, retreats, and professional events. | The maintained Seamly2D repository identifies the application as GPLv3+ open-source patternmaking software for Windows, macOS, and Linux. It reads multi-size measurement files for standardized sizes and individual measurement files for custom-fit work, publishes downloadable builds and releases, and links an active website and user forum. |
