When the weather, health or anything else keeps you in try ART!
There are lots of videos geared to kids; one is Art for Kids Hub on YouTube. Pick something and make art.
When your creations are too numerous for Grandma's refrigerator, take them to a nursing home or assisted living center for the folks who do not get visitors. Right now, amidst covid-19, there are very few visitors and most would be virtual or very short and at a distance. Some uplifting and inspiring art or calligraphy would be appreciated.
