Usage Skills 1. Determine the purpose: Before using thumbtacks, it is necessary to clarify their purpose. Thumbtacks are usually used to fix papers, fabrics, or other lightweight materials. Therefore, understanding the specific scenario and purpose you want to use will help you better use thumbtacks. 2. Choose the right size: Thumbtacks come in different sizes, so it is important to choose the right size. A too small thumbtack may not be able to fix the material, while a too large one may damage it. Therefore, when choosing thumbtacks, you should select the appropriate size based on the thickness of the material and your fixing needs. 3. Correct handholding method: When holding thumbtacks, use your thumb and forefinger to pinch the middle part of the thumbtack, which can help you better control the direction and force of the thumbtack. 4. Keep stable: When fixing materials, keep your hands steady to avoid the thumbtack deviating from its intended direction due to hand trembling. II. Usage Steps
