I know how you feel. Except, in my case, I daren't finish all of them...
I was allowed a small quilt (and my teddybear) with me in the psychiatric wards, but there are strict rules on the medical wards due to infection control. They don't allow flowers and cards, for example, the doctors don't wear ties and no-one medical is allowed long sleeves. Different hospitals have different regulations, so I would check, if I were you, that you would be allowed your quilt. It would be awful to take it and find it had to be sent home.
I was allowed my sewing with me, but they got a bit anxious about the needles, so I was only allowed one at a time. That makes sense, as a less careful patient could easily scatter a few and they don't go well with bare feet! Be aware of the rules for electricals as well. Some places are very picky (quite properly) about hairdriers, music-players and mobile phone-chargers. They may need to be tested before they will allow you to use the plugs.
I only mention this because, if you are anxious about your surgery, knowledge about the little things brings comfort. And with comfort there is relaxation and better healing.
Take good care, and I hope that all goes really, really well. Nel (Gadget Queen) And probably should write a Good Hospital Guide, at this rate!!! :(
