Complete beginner. Is carving small figures a hobby I can do from bed?

I am very unwell and have been mostly bedbound the last few years.

I have been really struggling with feeling like I'm unable to impact the world in any meaningful way, so I want to start a craft that has an end product that will last for a long time. Leatherworking, stone carving, whittling, etc. Of course most of these require energy, space, money, and mobility. All things I distinctly lack.

I have a buck knife and some super basic small carving tools, like the set you get in highschool art class to make lino prints and the like.

If I'm wanting to try carving some very small figurines to start with, is that something that I could feasibly do from bed with something laid down to catch the small pieces of wood?

Obviously sanding and varnishing and that stuff would require a proper surface, so it'd be more for the first stages. But I'm trying to get a feel for if I could dip my toe in to the craft as a passtime without leaving splinters on every surface within a few metres.

Any advice or thoughts are welcome, thanks in advance!
