First of all, buy more jewelry boxes to study, especially those books and magazines with jewelry pictures, and you can practice painting according to them. Improving painting skills is not only to draw naturally and smoothly, but also to grasp the actual proportion. You can use drawing boards and rulers, which are sold in Taobao and large stationery stores.
In addition, you should visit jewelry brand stores and specialty stores to learn about the market and styles. If you have the opportunity, you can go to the factory to learn about the technology and often go to jewelry-related forums to collect information, which is very helpful to improve the design level.
If you have the opportunity and time, you can learn 3D drawing software like Rhino, which can help you make your own inspiration and hand-drawn drawings into 3D models, realistic renderings and animated display drawings, which can be displayed not only directly, but also vividly to others. Rhino has a bright future in jewelry design and other industries. This software explains the teaching materials of jewelry, including the newly published Rhino 3D "From Introduction to Specialty", which is introduced in Baidu Encyclopedia. For more detailed information, you can go to the "China Jewelry Watch Design Forum", where there are many free materials about jewelry.
Finally, I wish you all your wishes! Realize your dream as soon as possible!
