Visual Arts is included in many Core Programs.
We plan to include other Creative Arts into Core Programs and Just Good Books soon.
If you are musical, artistic etc, share your passions and skills with your children. Learning an instrument or skill through 2 minute lessons works. When my children were learning an instrument, I would sometimes pop in and give them 2 minutes of help just when I could hear they needed it. This works.
Otherwise, consider enrolling your children in classes in your local community to expand on these subjects. These could be private lessons, homeschool group classes or lessons at a conservatorium etc.
