To add a row of chain maille, you add 5 rings, one to each column. 3 of the rings will be added as closed rings and 2 will be added as open rings. None of the rings sit perfectly flat, each ring has a raised edge. Note the position of the raised edge in columns 2 and 4, the raised top part of the ring is on the left - shown with a blue dot. In columns 1, 3 and 5 the raised edge of the rings is on the right - shown with a red dot. If your rings don't look the same simply turn the chain over.
