Pardon my ignorance but I'm still getting used to my Brother PE 770 embroidery machine and learning all the lingo. I've read several times to 'do a stitch out'. What exactly does that mean? I can't seem to find anything definitive on the web explaining it. Are you literally stitching the entire design on scrap to 'practice' before you embroider it on to your project? Is it just an outline of the design? Is it a particular function on the machine that I just haven't found yet? Just curious and want to do things right
