Acorn cap dye

Funny story....  I wanted to try acorn caps for dyeing.  My dear sweet girlfriend gathered  a bag full.  Plenty to make a wonderful pot of dye.  But I got greedy.... This past weekend my son and I went hiking and found a nice stash of caps lining the trail.  I gathered another bag to make ink and dye all winter.  Problem was - chiggers!  I didn't wear bug spray (tons of sunscreen, but really didn't need it in the woods).  So now I am covered with itchy bumps.  I should of been happy with the gift acorns. 
Silly me.

Used the dye on silk and cotton threads.  I feel that the silk must have a finish on it as it should of taken the dye better and darker than the cotton.  Still a nice colour.
