I cut the strips at 16 feet and 1/4 inch thick by 3/4 wide. Then I put them flat and touching on some plywood covered with plastic. Using wood glue I ran a bead along each seam then used clamps to hold the strips forming a single multi striped piece. Each one was 16 feet long and one foot wide. Those were for the sides of the pirogue.
When the glue set I removed the clamps and then ran a bead of epoxy along each seam to make sure they stayed put.
For the bottom I made a solid sheet with the strips and later trimmed it to become the bottom of the boat. Not sure about the size back ( standard Uncle John Pirogue ) then , say 36 inches wide by 16 feet long.
Both side panels and even the bottom bent without any problems to make the boat.
In summery .... All I did was to make the strips become a single sheet of striped plywood.
