The FFA is a relatively newer organization which took many years to get organized and accepted...it's known as the organization primarily for urban (city bound) middle and high school students whereby the local school sets aside land for raising crops and animal projects.
4H, on the other hand, the majority of members live on farms or ranches. FFA developed 20 or so years later and eventually became the competition of the 4H.
Neither organization sold or gave much in the way of jewelry...mostly had uniforms, hats, scarves and at times some mtal signs saying "A 4H Member Lives Here" or a variation thereof...purchased from catalogs
Do know the 4H gave pins for years of service...3 year pin and so on...
