I wash my flannel on warm and dry it on warm. Since I don't know anyone that uses hot water to wash anymore. But I also tell them they should wash the quilt in cool or cold water. If I believe the flannel will bleed then I would wash it twice and check again. The past few years I have not had a problem with bleeding. It does help to starch the flannel when you get ready to use it. It helps it behave and stay flat when putting the sandwich together.

I made a baby quilt for my DGD 6 years ago, pieced top and Minky back. It has been washed a lot in those 6 years and thrown in the dryer with the rest of the clothes, no special treatment. She still sleeps with it every night. If your dryer gets hot enough to melt Minky, it will be hot enough to melt your polyester and rayon clothing, and I've never heard of anyone's clothes melting in a dryer, even when using the ones at the laundromat, and they get very hot.

I agree, ALWAYS pre wash flannel as it also usually shrinks ALOT. Don't think Minky needs prewashing but it can't hurt just to be on the safe side.

If you are piecing the flannel, you will want to starch it as heavily as possible after pre-washing. Starch stabilizes flannel so you can cut and sew it without introducing unwanted stretch and distortion. Also, if you are piecing flannel, it's a good idea to use 1/2" seams on it, as flannel frays more easily than other cotton fabrics.

Flannel is a loose woven fabric (compared to your quilting cotton) which is why it shrinks up so bad. You will need to ensure it is washed at the very least the hottest temp the recipient is going to use. That way it will shrink as much as it needs to before you quilt it. Pre-washing is essential when using flannel

Minky is a polyester fabric. You do NOT need to pre-wash. If you do decide to pre-wash the minky, you need to finish the edges first. Either serge the edges or hem it. If you do not do that, your washer and dryer will be a stinking mess polyester is not a woven fabric, it will shed horribly. It will not shrink, other than the parts that fall off in your machine.

I have made 2 small blankets with minky. I read somewhere that the quilt top will shrink but the minky will not so it is necessary to wash the quilt top.

I did wash my quilt top before quilting them together. It was a thready mess that took some time to iron out but it made sense to me to prewash.
