any one familiar with wiccan/pegan

Hello my friends... My foster son's dad is wiccan/pegan (sp?) with Christmas coming up I thought I would get him a gift, but I dont know how they believe, do they even celebrate Christmas? If I am not mistaken they really dont follow the bible, but I thought that maybe I could get him something that would have to do with his "religion" (im not even sure if it is called a religion) any way would any of you have similar beliefs that could give me some advice?? I dont want to leave him out at Christmas time but I also dont want to offend him by getting him something that he wouldnt want.. Any help/advice would be greatly appreciated.. Shavon
