Flag of the Sami people (unofficial) - the colours (green and white), construction details and dimensions (proportions: 10:16, 4-2-4 and 5-2-9) based primarily on the description mentioned at Unofficial flags of Sami People (FOTW) and Sami People (FOTW). 
NOTE: This flag is not, and has never been, used to represent the Sami people. The source (FOTW) no longer mentions this design (and also earlier expressed doubt that the flag is genuine).
