I am making a new quilt and noticed the video suggests to be sure to cut off the selvages. I know in a lot of fabrics the selvage obviously should be cut off because it is white (off color compared to the fabric),and/or there is writing on it and that showing would not look good! Today however I am using batiks and the selvages just blend in so nicely. I don't see a color problem. I can't help but wonder.....is it necessary to remove the selvages when working with batiks? In general are selvages removed because they are stiffer and that will do something wonky to the finished quilt?
