I would second hand applique. I would find a nice project and prep the pieces ahead of time and take them with me. I will often prep a block ahead of time and take it with me when I know I will be sitting somewhere for a while. It's a nice way to enjoy my sitting around time. I love the patterns from Bee in My Bonnet personally, she does some of my absolute fave applique patterns. Let me know if you want a link to her site!!
Good luck!
