i love working with flannel & use it alot in quilting- i do not buy flannel from joannes, hobby lobby or walmart---
i always make sure the description says---double sided flannel...makes a huge difference
the best (in my opinion ) is Benartex double sided flannel & Moda Woolies flannels- they are great- i've also bought lots of great flannels from fabric.com and a few other on line sites.
