Long post, sorry, thinking a lot about grandparents as my last one, paternal grandmother is dying.....
maternal grandmother:
Saturday or Sunday tea from the trolley in the sitting room, always had to have open sandwiches of egg and cress or tongue made with white bridge rolls, then 'something to butter' aka tea cakes, scones or crumpets, and 'something to cut' aka lemon drizzle or coffee and walnut cake.
Sunday lunch in the dining room where never a pan could darken the door - all the veg etc had to go in special china dishes that had been warmed beforehand.
The little bag of soap pieces that she hand-made that used up all the last little bits of bars of soap so they didn't get wasted - that was in the bathroom. Thrifty from 2 wars
the TV that had an embroidered cover which she had made
antimacassers on the armchairs and sofa
sleeping bags on the sofas for dsis and me when we stayed the night
watching granny getting dressed in the morning and marvelling at how complicated it was - what with stockings hooked up to a corset, plus vest and hoooooj knickers, seemed to take forever to get into! Then she wouldn't dream of going out of the house without gloves and a hat.
sitting on her knee and stroking the incredibly soft skin of her cheeks and chin - I must have spent hours like that
having grammar, pronunciation and punctuation corrected endlessly - oh the pain for Harrogate Granny having dgds with scouse accents 
then paternal grandmother - actually my DF's step mum but always treated all of us (14 in total) as the same, whether DGC or DSGC, just a lovely woman
lying on my stomach on the bed in the tiny room I stayed in - called the rabbit room becuase it had a rabbit door-knocker - reading tintin books that had been my dad's
scaring ourselves peering over the bannister on the top floor and looking down 3 storeys to the groundfloor
scaring ourselves even more playing murder in the dark with older cousins in the basement
hiding out in the summer house at the bottom of the garden - huge long garden so nobody in the house could see us
playing frantic games of racing demon at the dining table - we could get 15 of us round the table standning up and you each needed a pack of cards for the game to work.....madness. My DGF made that table out of a door in about 1957. Saw it at DGM's house the other day when we were clearing it out for sale - would have loved to give it a home but no space here so it will probably go with the house clearance people 
being amazed when, at my aunt's wedding breakfast which was back at the house, DGM produced box after box of M+S choc eclairs as pudding for 100's of people - this was the height of sophistication to me!
so much love and laughter
