I have never seen anyone in the Sewing Machine shop, nor have I ever known anyone who bought anything from there.
It is one of the many shops in Llandudno that I have been mystified about how they have kept open over the years.
The so called 'Shropshire Oat Cakes' shop, (ex Fruit and Veg, Barbers, Whistle-Stop Cafe...etc.. etc...) is one that I can never understand why it has NEVER opened. Bizarre.
