funny how one person is taught (or just told) one thing and they believe they are RIGHT PERIOD! lots of discussion about what is raw edge & what is not... some of us were taught- raw edge was an easy- technique where you can use fusible or not and then machine stitch- with what ever stitch/method you choose- the edges are not turned under (hence 'raw edge') or you can hand applique- "needle turn" where the edges are not 'raw' they are turned under and the stitches are made in the fold- how you choose to finish your raw edges are your choice- there are lots of options- zigzag, blanket stitch, straight stitch, satin stitch, other decorative stitch...anything goes. don't be 'the quilt police' and demand only YOU have it right- there are many, many different techniques- with new ones coming up all the time- plain & simple- difference - raw edge- edges not turned under- finished edge - edges turned under.
