The rest of the moccasins are either children's or baby moccasins. They also are all Plains tribes.
Though older, early moccasins wouldn't have used colored leather. They did use natural dyes and dyed porcupine quill work was used by the tribes in the Northeastern U.S.
The bottoms of these are made of parfleche (brain tanned deer hide) and are sinew sewn. Moccasins from the northeastern U.S. were made from moose hide and smell smoky from the tanning process.
