We've been making deer hide rattles in class for our studies on Native Americans.
We soaked the two blanks to soften them, then the kids began to sew the two pieces together.
After they were done sewing they filled the rattles with bean to let them dry in the correct form.
They then had to cut their handles from a birch branch. The only step left is to dump out the beans save a few, then attach the handle. Presto!
