Further, your kids seeing you do these things will think you are the best at it or will be enthralled trying to emulate superior efforts with you. I can't paint. My painting efforts are embarrassing. My daughter, keen on painting, saw my horrific effort today and thought it was amazing. If we watched an artist on YouTube and then tried to paint together, she would absolutely enjoy that too.
If you don't have an internal appreciation of simple crafts (gardening, making something) then your children can help you find purpose in it.
Allow yourself to do things that others do better.
You do not have to be the best.
You will enjoy life much more. Your kids will, too.
