natural dyes / berry potluck

I really want to dye a piece of fabric purple. I gathered up everything I could find in the yard that was in that colour family. Everything went into the pot together:

grapes
pokeberries
elderberries
blue berries
black beans
hibiscus
hibiscus tea bags
grape juice (in the freezer since 2013?)

I really need to remember to wear gloves!

The colour is lovely on both pieces of fabric I dyed, but not very purple... Plus I have read that most of what I use is fugitive... probably won't last long.  But - I did have fun!

ps..  I used iron mordant
