The smell of warm varnish and books in our public library - it had oak panelling and a carved wooden staircase up to the reference room upstairs, so the scent was quite noticeable.
My mum's friend bought us (Dsis and I) really lovely Christmas presents: a china horse with tiny leather saddle and bridle, a tiny doll in an egg pram - we got miles of play out of those, we loved them. So simple but totally engaging for some reason
Scraps and Hollie Hobbie stickers - just for the smell alone but also the texture and colours of the printing on the scraps was just glorious
Viennetta for pudding. So decadent! Loved the steamed pudding in custard for school lunch as well, it was sad when we had to take a packed lunch instead
Multicoloured Swop Shop on Saturdays and The Monkees, The Flumps, The Red Hand Gang in the summer holidays
As mentioned by others, the Letraset Action Transfers. They were SO much fun
The day our comics were delivered: Mandy, Bunty, Warlord, Roy of The Rovers. We all read them all, not just our own
Sending off for things - we collected loads of Tudor crisps packets to send off for the Flutterbys. The joy when you got something in the post and it was a flock butterfly you could pin up somewhere...
