If you want to start embroidery you need a few things. A needle, a thread and a fabric. It is much better to stretch the fabric, so you can stitch easily. The easiest way to stretch a fabric is hoop.

You push the needle up from below the fabric (remember to hook a thread first) and then you push the needle down in the point "B".
