How nice that you are able to share your sewing love with your DGD during her annual Canadian trips! Good memories for you both.
The question that comes to my mind is ... does she need shears?
Speaking for myself, I find that I so seldom use shears, and opt for the rotary cutter more and more.
Re IceBlossom's suggestion re Kai scissors ... I've heard a lot of good things about them, but have never used them, myself. As mentioned, perhaps it is beyond your pricepoint? With that in mind ... could you have them shipped to her Mom, and just give her one or two pairs for Christmas? Keeping the other for other gifting times?
A Great Grandmother you are!
