I have a BL Symphony and use #7 (zigzag) on my applique. I do not care for my stitches to show so I set it for .05 width and .09 length and use the same color thread as my applique. I use the "N" presser foot because it lines up perfectly with the center needle setting on the Q07 setting. Here is a sample of my applique close-up. Just another option, if interested. (this is turned edge so stitch may not be the best for raw edge so you'd need to consider this.)
