First, was the fabric washed before you made the quilt? How intense are the colours? If it's never been washed bright fabrics you will need something in a gentle wash in case the fabric bleeds. If it bleeds do not dry the quilt which will set the marks.Will your fabric bleed even if pre-washed? sometimes. I always use Shout Color Catchers in the washer the first time I wash a quilt.
I have never used a wool batt so check the packaging for the care it requires.
