I use one duck skin for each adult's outer slipper. Smaller birds are used for smaller feet.

Inuit on the Belcher Islands have often depended upon bird skins rather than caribou skins for clothing and over-slippers since ice storms in the 1870s eradicated the caribou population. Eider duck skins have been used to make clothing and footwear that is very warm, light-weight and water repellent. Eider duck overshoes are favoured by men and women both in camp and when hunting as an insulating layer.
