I couldn't not use some of the leaves from the beautiful little red Maple tree that's in the front of our house. I picked some of the really red leaves, laid them out on a little piece of prepared cotton. I rolled the fabric up with the leaves inside and stuffed the works into a little jar.
Almost immediately the liquid started turning purple. After a few days, it was a beautifully deep purple.
When I unrolled the fabric, I was surprised to see 'stripes'. You can see a black skeleton of each leaf. Here is the fabric, which is purple, and some of the leaves, which are still red.
