Thanks for all your replies. I really don't feel that I can take on this job as I am just not good at that sort of thing. My friend just saw me knitting and thought I could do it. I have suggested - and she agrees - that she ask her friend to give her back the item, then give it to me and I will take it to our lys lady who also does sewing repairs and ask her for her opinion. It's not even my friend's friend who knitted the thing, but some lady that she knows.
