I saw the Gingerbread lady today (the one who wrapped her gingerbread for our Summer Sale in Press 'n Seal.
Unfortunately she is just recovering from knee surgery and said it had affected her brain too! As far as she can remember it is called Press 'n Seal and she bought it at either Lidl or Aldi (the cheap supermarkets) in Lowestoft. I go there very seldom, so can't just check, but she did say that next time she goes she will bring me some, and then I can check the name. However, as she is still on crutches it may be some time.
I explained why I was asking, but she was a little bemused, not being a quilter!
So, if you have an Aldi or a Lidl nearby, try those. She says it is much better than clingfilm!
