A student wants to teach a friend how to sew. Which type of medium should the student use?

The student could use a combination of different mediums to teach their friend how to sew. Some possible mediums could include:

1. In-person demonstrations: The student can physically show their friend how to sew by carrying out the sewing tasks themselves while explaining the steps.

2. Video tutorials: The student can record videos of themselves demonstrating various sewing techniques and sharing tips and tricks. These videos can be shared with their friend who can watch and learn at their own pace.

3. Written instructions: The student can create written instructions or handouts that outline the different sewing techniques and steps involved in certain projects. These can be shared as physical copies or as digital documents.

4. Online resources: The student can recommend websites or online sewing tutorials that provide step-by-step instructions and visuals to help their friend learn how to sew.

5. Practice materials: The student can provide their friend with fabric scraps, needles, thread, and other necessary sewing supplies so that they can practice the techniques taught.

Ultimately, the choice of medium would depend on the friend's learning style and preferences, as well as the available resources and the level of complexity involved in the sewing skills being taught.
