Not sure what the snowball looks like but it sounds difficult. I am going to decide tomorrow because I want to start/finish it this weekend. My brother has terminal lung cancer 9never smoked a day in his life!). He was very ill three weeks ago and we thought we were going to lose him but he was transferred to a wonderful hospital in Newcastle and they have treated him. We expect him to come home this weekend but are not sure what the future holds. I believe in miracles and everyday he is still with us is a miracle to me. Thanks so much to everyone for all the suggestions and also for prayers. Will post when I decide and hopefully will be able to show you all the finished product on Monday. Eileen
