Rag quilts can have designs too. While I do prewash the flannel, once the quilt is made and the edges snipped I take it to the local laundromat to do the final wash and very long [mostly without heat] ragging and drying.

It is fun to see how much thread comes out at the laundromat.

I made a string quilt out of all flannels in girl colors and it turned out great. I plan to do one in boy colors also. I found it very easy to work with. I did prewash the flannel.

Thank you all. I have decided on a rag quilt. Great advice from everyone.

I agree with ckcowl, ive used flannel in the samepatterns as cotton patterns. No problems

Just a note of caution. I think rag quilts might fray or easily be chewed and become a choking hazzard for babies.
