How to Tie a Tack Knot

Use a needle and thread for a tack knot.

Sewing uses a needle and thread to control fabric. A seam joins pieces of fabric along a line. A tack joins fabric at a single point. Use tacks to join two items without creating a visible line on the outside of the garment. Tack a band of ruffled trim around the inside edge of a sleeve to make a ruffled cuff, or use tacks under the wearer's arms to keep a flowing dance costume in place.

Things You'll Need

• Needle
• Thread
• Scissors

Instructions

1. Thread your needle with an 30-inch length of thread and knot the ends of the thread together.

2. Pin all the layers of fabric together at the point you want to join them.

3. Stick your needle through all the layers of the fabric at this point. Bring your needle through from the back to the front.

4. Stick your needle back in 1/8 inch from the place it came out and stitch back through the layers of fabric the other way. Pull the thread tight.

5. Sew two more stitches in the same way.

6. Knot your thread loosely near the fabric, making a 3/4-inch loop of thread.

7. Stick the point of your needle through the loop of the knot and into the fabric at the point where the thread is coming out of the fabric.

8. Pull the thread tight to make a small knot very close to the fabric. Cut the thread 1/8 inch from the knot..
