Using design elements from well-known brands when selling homemade goods can be a legal risk, as these elements are often protected by copyright, trademark or patent laws. To use these elements without violating the law, you can consider the following points: 1. **Original design**: Make sure your design is original. It’s okay to be inspired by someone else’s work, but be sure not to copy it directly. Try to incorporate your own creativity and style to create something unique. 2. **Public domain**: Use elements that have entered the public domain and are no longer protected by copyright. You can find and use such designs, but you need to confirm that they are no longer protected. 3. **Imitation, not copying**: When designing, only adopt the essence of the style of a well-known brand, rather than the specific design. This means capturing the characteristics of color, form and style, but not directly copying their trademarks or logos. 4. **Variation design**: Make obvious changes to the borrowed design elements to make it different enough from the original design. This strategy is called "variation use", but it still needs to be cautious because the changes need to be significant enough to avoid being considered infringement. 5. **Permitted use**: If you really want to use a brand's design elements, you can try to contact the rights holder to negotiate a legal license for use. Although this may bring additional costs, it can avoid infringement disputes. 6. **Legal consultation**: When in doubt, it is best to consult a professional intellectual property lawyer. They can provide specific advice to help avoid potential legal risks. 7. **Market research**: Learn how other designers and brands deal with similar issues, which may provide some inspiration and compliant solutions. In short, in the design and sales process, try to maintain innovation and legal compliance to build a good brand reputation and avoid legal troubles.
