1. Back stitch. It can make a thread similar to that of a sewing machine. During the sewing process, a short backstitch is performed at the needle entry and closing points, which will make it stronger. It can also sew many small expressions, as shown in the picture below.

2. Hidden stitch (hidden stitch). Fold the seam allowances of the two pieces of fabric inward and sew using parallel inner needle movements (as shown in the picture), as shown in the picture below.

3. Sew around the needle. After folding the seam allowance in, insert the needle from the seam allowance and place the knot inside, as shown in the picture below.

4. Flat stitch (joint stitch). The thread is short and the spacing is long. The thread on the front is short and the thread is long on the back. It is mostly used to sew the filling opening after filling with cotton. First, flat stitch and then pull the thread, as shown in the picture below.

5. Overlocking seam. Insert the needle through the back piece, then through the front piece, turn around and pull out the adjustment suture. It is mostly used for sewing non-woven fabrics, as shown in the picture below.
