I have never used natural dies from flowers and wondering if anyone here has done it. Is it better to use vinager or salt to set the die. My morning glories went wild this summer and I still have 100's of blossoms. Every time I walk by them I get a stain of purple on my clothes. It gave me a idea of taking the blossoms cut them in half and press the morning glories right on the fabric. They are a beautiful deep purple with a hot pink centers. Can anyone give me some pointers? I want to make a table runner for my table and crochet a boarder around it.
