I had a lady bring a beautiful hand embroidered quilt top to me and a beautiful batik for me to add the borders to it,
Well since her quilt was all hand done and on white, I decided to wash the batik first and it really bled so I call her and told her and she brought me another fabric but this time a light purple bella solid thenks went well from there.
So I would never use a batik without washing it first. JMHO
