Bamboo yarn is SO soft! I loved working with it to make some baby toys years ago. You mentioned looking for small projects to do for charities- many folks make hats and scarves for shelters and newborns. There are many different groups that collect the knitted items, or you can donate them directly where you see a need.
Thanks for your project ideas @jamethiel. I'm looking forward to getting stuck in. First I need to find my wool stash and see what I've actually got! 😁
