The skill level varies depending on the course itself. Some courses are designed for beginners, while others are better suited for those with intermediate or advanced skills. If you're a complete beginner, you might look for courses that offer an introduction to basic knitting and crochet techniques, such as needle and thread usage, basic stitches, pattern reading, and simple project instructions.

While online course structures vary widely, most online knitting and crochet courses are designed to provide detailed instruction on techniques, patterns, and projects, as well as additional resources to help you develop your skills. Courses are often divided into modules with video lessons and may include lessons on how to create and execute knitting and crochet projects, with detailed instructions and support to help you successfully complete your projects.

While the answer may depend on the course provider you choose, most offer a certificate of completion at the end of the course. However, they often require additional requirements, such as completing a specific project or successfully completing an assessment. It's worth noting that these courses may charge an additional fee for the certificate of completion.

Courses can generally be accessed on a variety of mobile devices, such as smartphones and tablets. All you need is a good internet connection to load the lessons. It's important to note that some online courses may require downloading a specific app or software to access the content.
