I need to make a rainbow-pattern fabric - 15 yards? - to be used to construct stoles for priests - for Cursillo use.

I've never done fabric painting! Don't know where to begin! I want to do this one task - and then, not do it anymore.

I'd like to make fairly narrow diagonal stripes - I think. I want the shades to blend together softly - nothing real bright.

I've heard that you can even do this with water-based house paint! What a concept!

Suggestions and directions,please!

Thank you!
