Same here, although waiting until children back at school (holidays only astarted today) but have been making lists.
I am planning on starting at the top of the house and working down -
Streamline bottles etc in my bathroom
Thin out mine and dh's clothes
Declutter dh's office and ensure all filling etc up to date
Declutter lo's rooms - charity shop/dump outgrown clothes, toys, books and sort both their bathrooms
Decorate ds's bedroom
Sort out and update airing cupboard (bedding/towels)
Redecorate downstairs cloakroom.
Empty all kitchen cupboards wash and restock (getting rid of equipment we don't use and anything out of date)
Paint kitchen ceiling
Strip wallpaper in living room alcoves and redo (yet to choose design)
Sand and oil dinning table and chairs
Buy new choc brown leather 4 piece suite
Declutter and paint utility room, put up shelving and storage (already bought and waiting in garage to be assembled), then replace everything so room is more useable.
Declutter lower ground floor hallway and buy more sorage units.
Sort playroom getting rid of broken/outgrown toys or stuff they don't play with. Repaint wall ds decided to graffitti on.
Clear out boxes in garage (mostly outgron childrens' clothes and baby furniture etc).
Half a tonne of weeding/thinning/replanting in garden.
Shampoo all carpets and sugar soap all walls and woodwork.
I plan to have it all done by the time my parents come to stay to look after the children whilst dh and I are away for a week in Chicago (any chance I will ?!?!?! ).
