For the uncut turquoise, wash it with Retayne, not Synthrapol, to set the dyes. You may have to do it twice and be sure the water is at the required temp of 140ºF. Then wash again (or test as below) to see if it's still running.
If you have a front loading HE washer, you can use Dharma's Dye Fixative as a substitute for Retayne, soak the fabric in it in a bucket and then wash in the machine as suggested by Paula Burch, master dyer, or hand wash with Retayne (you still need the 140ºF water temp though and it must be stirred for 20 minutes).

For the quilt top, you don't have to wash it to find out if it's going to run. Use a damp Q-tip or a white paper towel to test each fabric for possible loose dyes. Rub or blot the fabric surface and see if the Q-tip picks up any color. If it does, at least you'll know and can act accordingly. Do not use Retayne on the top, use Synthrapol for that as has been suggested. Be sure to follow product directions carefully for all of these products.
