Help with zig zag on applique
I know that this seems like a very basic question but I'm confused. This will be my first time doing an applique with zig zag. I looked at 4 you tube videos and all seem to differ. One says keep both sides of zig zag even catching both sides of fabric, the other says concentrate on keeping it on the inside of the applique. Then there is the length and with. I did do a practice applique and I did not like the results. I need some guidance.
