Hi Hazel. The girls have given you some great websites to look for headgear. I didn't bother with a wig either but if I was working, it may have been a different story though. I did try on some wigs and I felt they were too hot and itchy for me.
I just got myself some colourful scarves and twisted them around my head. There are some YouTube tutorials on how to tie scarves and I soon got in to the swing of some creative twisting. I found it very simple to do too. I find I look at scarves in shops now rather than clothes :) Just a tip though, don't get any silk scarves as they can slip off your head. Easier to go with cotton.
Deanne mentioned the Look Good Feel Better workshop which I found to be very helpful. I'd highly recommend going if you haven't been already. You can book online at

Good luck with whatever you decide to do Hazel.
