What did they use to make the copper inuit kayak?

Copper Inuit kayaks were traditionally constructed using a frame made from wood, typically driftwood or other available timber, which was then covered with a skin made from animal hides, such as seal or caribou. The frame provided the structure, while the hides offered waterproofing and flexibility. In some cases, they also used sinew for lashing the frame together. This combination of materials allowed for a lightweight yet sturdy design suitable for navigating Arctic waters.
