MORDANT MONDAY: Post-Mordanting Cotton

We get mordant questions all the time at Botanical Colors so why not create Mordant Monday??? Got mordanting questions? Email [email protected] I recently used Logwood and cochineal on old cotton sheets as blankets to put over watercolor paper when eco printing books. The cotton blankets came out so amazing I decided to sew them together and make a kimono. I had no intention of making a garment or I would have taken more pre-care with the fabric. Since these were very old sheets, I didn’t scour as I’ve laundered them for literally years. I did not mordant either. Anyway, here’s … Read more

MORDANT MONDAY: Mordanting Cotton & Freezing Clothes

Deciding which mordant to use comes down to the types of fibers you want to dye and how much time or energy … Read more

It’s a fun and easy project!
