The kit contains 12 pieces planed two faces, air dried for best steam bending characteristics; the four INNERS are 1/4" x 1" x 40" and the two outers are 1/4" x 7/8" x 40.
The sets are assembled so that the two exposed face pieces are White Ash while the four inside pieces are White Cedar.
All 12 are steam bent at one time but the glue up is done with the 4 inners separated from the 2 outers; information is in KayakCraft.
