My favorite straw purse has become really faded. Could I revitalize it by brushing on something like RIT dye? What would be more colorfast, liquid or powder? I don't want the color to come off on my clothes. The purse is real straw and the shoulder strap is cotton rope.
You could dye the straw purse with a natural black walnut husk dye. I had a neighbor give me a basket she made and it was dyed from the walnuts on our property. Turned out very nice.
You might inquire advice from a basket weaver or a college that holds classes in basket making to learn what dyes are used that will not run.
