Too addictive! I have a soft spot for jigsaws. I was fortunate enough to spend a lot of my childhood time with my grandparents, as Mam had to work.
My paternal Nain (grandma) was brilliant at keeping a young child occupied. We did a lot of jigsaws, so my jigsaw skills have been honed. Lots of her jigsaws were from jumble sales though, so usually had at least one piece missing. As soon as you got bored of one thing she would have something else…card games, drawing and painting, helping her do her laundry, polishing her brass, exploring her attic (a treasure trove, of all sorts…jars containing ‘special shells’) etc. She had a streak of fun in her…which I think my cousins and my younger son have inherited. I’m just too serious for my own good.
