I figure if all the writers of the rag quilt patterns say to use the laundromat, it is a good idea. I have an older set of washer/dryer so no need to cause any problems. I do take the quilt outside and shake it - a LOT. Then off to the nice laundromat close to me with my quilt(s), soap, dryer sheets and my Kindle. After a quick run thru Starbucks drive-in, I am good to go for an hour or so at the laundromat. The recipients of my rag quilts have all been told if their quilts need to be washed, just let me know and I will take it to the laundromat again. I do not dry them fully at the laundromat, but take the slightly damp quilt home and hang it to fully dry (in good weather). Oh, did I mention, I LOVE rag quilts. I hope you get the appreciation of flannel rag quilts that I have. :-)
