yap regular sewing.... according to my teacher there are 100 different kinds of sewing.

Of course! There are many different types of stitches used in sewing, and I can certainly help you understand them. However, as an AI text-based bot, I cannot show you actual pictures, but I can explain and provide descriptions of each stitch. Here are some commonly used stitches with brief explanations:

1. Straight Stitch: A basic and commonly used stitch. It forms a straight line when sewn. Typically used for sewing seams or creating simple decorative stitches.

2. Backstitch: Similar to the straight stitch, but it involves sewing backwards first to anchor the stitch. It creates a stronger and more secure seam, commonly used for sewing seams that need extra strength.

3. Zigzag Stitch: This stitch creates a zigzag pattern when sewn. It is primarily used for finishing edges to prevent fraying or for creating decorative stitching.

4. Basting Stitch: A temporary, long, and loose stitch used for holding fabric pieces together temporarily. It allows for easy removal or adjustment of fabric before sewing a permanent stitch.

5. Blind Hem Stitch: Often used for invisible hemming, this stitch creates tiny, nearly invisible stitches on the front side of the fabric, while catching a small portion of the backside. It results in a discreet hem finish.

6. Overlock Stitch: Also known as a serger stitch, it is used for finishing raw fabric edges to prevent fraying. Overlock machines commonly perform this stitch.

These are just a few examples of the many stitches available. You can search online for visual references by using the names of these stitches for more detailed images.
