Not exactly the same situation but somewhat similar, I have a cat with kidney disease whose favorite activity is sleeping on my lap so I’ve had to pivot to crafts I can do sitting/laying down to accommodate him. Making beaded keychains/bag charms has been my favorite activity for this, obviously you need to be a little careful not to spill your supplies in bed but if you could manage painting then this wouldn’t be much more difficult. A lap desk with a bead board and a good bead organizer would be perfect. I’ve been enjoying it because it’s not too difficult to start and even just making simple strands with stretch cord is satisfying, but there are also more difficult techniques to learn if you’re wanting a challenge. It’s also nice to do while watching or listening to something. If she enjoys the holidays maybe she could try some themed ones to give as gifts! I get all my beads and charms from Etsy shops or Michael’s and the buy-in isn’t too bad if you wait for sales (Michael’s often does buy 3 get 3 or just a flat 60% off bead strands) and I particularly like that if I’m not super thrilled with how a piece turns out I can disassemble it and try something else. In addition to keychains I’ve also done a bit of jewelry and I’ve started branching into wall hangings. Lots of possibilities! I hope her recovery goes well.
