It is 100% cotton fabric with the look of homesprun. It comes in natural, white and some colors. Lately, I have been having trouble finding it in white. I only use the white or natural...and the natural(sort of oatmeal colored) works even with white. I buy it at Joann's with a coupon, usually by the bolt, but most purchase it by the yard. I have made so many flannel raggety quilts and this just gives the edges such a beautiful, puffy look.
I have made some that have embroidered blocks so that the quilt "tells a story". I will try to see if I have some pics and put on for you so you can see the edges. Hope this answers your question.
