Natural Dye – Sumac bark/twigs

Photo of two index cards laid out on a white table. The top index card has written information detailed in text on this page for the sumac bark/twig dye.

The bottom index card has 5 dye samples stapled to it. There are 4 fabric strips in linen, linen/rayon, bleached muslin, and natural muslin and 1 cotton yarn. They are all in shades of a light greyish tan color. The linen/rayon is a little more grey than the others. The natural muslin is a little more brown than the others.
