Hand embroidery has tons of places online to learn with. I learned how to chain stitch at a very young age. Then the French knot. My grandmother taught me so I could do some work with thread while she was sewing. It is very peaceful. When they introduced silk ribbon to embroidery, that kicked it up a notch. Machine embroidery is a different thing all together. Pick out what you want... position your fabric and hoop and, ideally, press the button and off it goes. You can't use your machine while the embroidering is going on. Great way to monogram things or if you have the right machine you can put your own designs into the computer program and it will do it all for you.
Good luck!
