Royal Stewart Scottish tartan 80th birthday invitation. This tartan is the famous Royal Stewart or Royal Stuart tartan and is one of the best-known tartans. It is associated with the royal House of Stewart and is the personal tartan of the British monarch. This tartan is also worn by the pipers of the Black Watch, Royal Scots Dragoon Guards, and the Scots Guards, as well as a select few civilian groups that have been granted permission by the monarch. Theoretically, this tartan should not be worn without the express permission of the British monarch. However, the Scottish Register of Tartans observes that in practice, due to its popularity, it has become a universal tartan, which can be worn by anyone who doesn't have their own clan tartan. "In the same way that clansmen wear the tartan of their chief, it is appropriate for all subjects of the monarch to wear the Royal Stewart tartan." A perfect tartan for a birthday invitation! Change the wording to any year. It's very versatile. All the fonts can change as well in the design tool. Use it for any other occasion as well. The back of this version of the invitation features the full tartan design without any wording.
