At the same time, the holding force should be moderate to avoid excessive force leading to hand fatigue or injury. 3. Fix materials: Thumbtacks can be used to fix materials together during sewing or patchwork. Insert the tip through two or more layers of material and gently bend the tail to make the materials closely adhere to each other. 4. Precise stitching: During stitching, thumbtacks can be used for temporary fixation to make more precise stitching. Remember to pull out the thumbtack after stitching to avoid leaving traces.
