It's a good idea to knit a hat for my mother-in-law. It doesn't cost much, but it can fully express my heart. People around 45 years old, well maintained, will look very young, so the color of the hat should not be too bright, but neutral and tasteful. I collected a video of hat knitting /b8346 14/d66693749.htm to see if there is any. Colors are for reference only. You should also consider whether it matches your mother-in-law's usual clothes. If not, I still have hat patterns in reality, which I can discuss with you.
