Don't buy any pre-cuts of flannel. period. Buy yardage, prewash once or twice. Dry in hot dryer. If you don't believe me, Measure your flannel pieces, write down all your measurements. Take photos on your cutting board or other flat surface, Before your pre-washing. Then lay out and re-measure AFTER washing, drying and ironing your flannel pieces. Throw a couple FQ of both your Flannel and a trusty quilters cotton into the same washing, it might be easier to get persuasive measurements from a FQ. You need to convince yourself, not just listen to any other advice. But remember "Not all Flannel Fabric is Equal." Do some research and read up about what makes Quilters' Flannel different than other weights. Good luck, and please share with us on Quilting Board your results.
