Okay, before we can start machine sewing, you need to be familiar with basic hand sewing techniques. All of these are still used when making clothing or in basic sewing, as well as embroidery etc. I know it is tempting to start out with a project like a skirt, jacket or pillow. but let's just get out feet wet before we start swimming.
If you're a novice to sewing I suggest you try out these stitches and knots for yourself so you can get familiar with them.
Note: Most of the hand embroidery techniques photographs are done on embroidery gauze with embroidery thread. This to make it clearer on the photographs. Normal sewing thread will be much thinner.
