Don't know if this is too late or not...
You might want to test the color fastness of the embroidery thread, especially if it is red, purple or similar dark color. Just dampen a paper towel and blot against the embroidery. Check to see if any of the color has transfered to the paper towel.
I also always machine wash quilts for the first time with a color catcher sheet (http://www.shoutitout.com/family_catcher.asp) on cold water. The cold water will help set the colors and the color catcher sheet will help if there are any bleeds.
