Are mercerised cotton fabrics okay?
I have been given a bag of fabric off cuts from an acquaintance who sews sheets and pillow cases at home for a company. She tells me the fabric is very good quality pure cotton but it feels a bit "smoother" than the fabric I buy at the LQS. Could this be because it may be mercerised and if so...is this a bad thing to be quilting with? I have done a burn test on the fabric and it burns like cotton but does not burn completely once away from the flame and it leaves a black ash that doesn't "powder" when touched once cool. Advice? Opinions?
