Take two weavers and place them adjacent to each other so that their ends are on the inside of the tray, protuding about a half-inch. See the first photo.
Hold these ends down with fingers from you left hand. Pick up the left-hand weaver, take it to the inside of the tray over the weaver to the right, behind two stakes, and then out towards you. See the next photo.
Take the 2nd weaver to the inside of the tray over the first, behind two stakes and out as in the next photo. Repeat this pattern of "behind two and out" until two stakes remain. See the next photo. Take the left-hand weaver in, over the end of the weaver that you began with, cut its end so that it overlaps that weaver and sits with a half-inch overlap on the inside of the tray. Repeat with the last weaver.
Begin a second row of twining on the next side to the right. Complete that row.
