I am experimenting and playing with natural dyes, and, have saved the leftover "tea" from our last few batches of hydrosol. The water lleft over from distilling the eucalyptus hydrosol was a really, REALLY interesting red color. I used some of the actual eucalyptus plant matter to compost dye some silk squares...those won't be ready for a few weeks, so I don't know what they look like. But I dyed this roving with the eucalyptus "tea" and think it's a really pretty color! Next, I'll try the leftover tea from the lemon eucalyptus we did a week or two ago. :)
