I agree with others about prewasing. However, if you are giving this quilt to someone with chemical sensitivities, you might ask them what to use. I use Orvus to wash my fabric and quilts and even my bro, who has major chemical sensitivities has no problem with it. But, if all you have is Tide, consider a double rinse or just giving it to that person unwashed.
Another issue. I spent nearly $ 300 to get my Mom's quilt quilted. The quilter did not preshrink or use a batting with minimal shrinkage as requested. I was horrified how much the batting shrunk, ruining the original quilted look. All the whimsical butterflies and dragonflies and birds disappeared into homey lumps. My mom was very disappointed. It was 2 years before she could bring herself to use the quilt again.
