I recently made a lime and yellow baby quilt for a friend's great-grandbaby and washed it before giving it away. I used "Quilt Wash" from the quilt store and put in a white towel as a color catcher. (Since then I bought a box of the real ones for my next quilt.) I washed on delicate, warm water. But I spread it out on my cutting table right from the washing machine, pulling and stretching it, and smoothing out the top so it was nice and square. Left it till it was just damp, then put it in the dryer to complete drying. It looked just fine.
