Flag of Ohio [SEP] Folding the flag
A method of folding the flag of Ohio was created by Alex Weinstock, a Boy Scout from Junction City, for his Eagle Scout service project. It requires two people. The procedure was passed by the 125th Ohio General Assembly as House Bill 552 and signed into law by Governor Bob Taft on February 15, 2005: Ohio is not the only state that has designated a folding procedure for its flag; however, Ohio's procedure takes on special importance due to the flag's irregular shape. A flag vendor in Arkansas has described the procedure as "quite a challenge".
