Hello Wendy, welcome to the GMB - and our thanks for your contribution. We appreciate that the loss of your mother was not that recent, but nonetheless we all send our condolences to you, since I know how much Mums mean to all of us.
Having now read your mother's book, I can certainly confirm that this is an invaluable addition to anyones library of glass related books - and very useful to know that you do have copies available still
note to mods. perhaps Wendy's email link can be preserved somewhere appropriate?
