Yummy berry colored silk

Look what my roommate tripped over on her way into the house today! Some little thread fairy dropped these off on my doorstep without a note or anything. Looks like my friend Renee has fired up the dyebath again. I just love the berry colors, good enough to eat. The tags say cochineal and indigo. One of the colors is a bit grayer than the others, did she mordant with iron instead of alum? I don't know, I am no dyer so I'll have to ask Renee. These are so pretty they deserve to be used in a project. Soon...
