Thanks everyone for your suggestions, you will be pleased to learn that rubbing alcohol did work on all but one circle and for some reason that just wouldn't move. Am thinking maybe that was the first one or the last one I ironed.
You do have to go very gently tho and use a cotton bud. We can not get "Sure Clean" or "Goo Gone" here in NZ so was unable to try them.
Once again I do appreciate how quickly you all responded to my cry for help.
Best wishes to you all
Yvonne
