Learning from a senior person sounds like a great idea! I can crochet a little, but I'd like to learn more from someone who is experienced, and it sounds like this might be an ideal way to do it.
I know many older people feel like they no longer have anything to contribute. They feel useless, when the opposite is actually the case.
I think it would be wonderful to learn a skill, make a new friend and help someone, all in one! And these older ladies usually know how to do beautiful work. I’d learn to love to learn from them!
