fabric fraying on applique
I am working on a "piano quilt', which will have a large piano appliquéd in the center. I did not use fusible interfacing under the whole piece, just few in few points, enough to stabilize it in place. The black fabric is batik and as you can see it is fraying a lot. Not sure what to do, should I try to trim the fraying or maybe my stitches are not dense enough. Any advice or points from You, more experienced quilters? thank you
