I had an interesting experience today. I had made a few pillow presentation cases for Quilts of Valor, and I washed them since they want the quilts/cases laundered before presenting them to veterans. I put in two color catchers as a precaution since there was some blue. Much to my surprise, the blue fabrics were fine but one of the cases has a bright yellow print. Guess what, the color catchers came out yellow! Luckily, they did not bleed onto the white fabric sections.
