After reading Carolyn's blog at the weekend, and knowing that I had blueberries in the fridge past their sell by date, I had ago at using them for dyeing. The hardest bit has been the wait- but it was worth it. The fabric and threads are a lovely soft heather colour.(sorry forgot to take a picture of the threads. Fabrics used from top to bottom :-
Gauze(from out of date first aid kit)
Knitted 100% polishing/cleaning fabric- Asda
It was so easy, not having to worry about mordants either.
