We start a few things at the start of advent.
I get some stuff out from storage - DD's Christmas fleece blanket, her Christmas duvet set, the advent calendar (fabric one with pockets), and a favourite snowglobe.
I usually also take out a Christmas mug each (only 1 each, I don't want to lose DH to the Christmas Grinch so early on!), DD's old Santa plastic plate, bowl and tumbler, and the Christmas storybooks and movies.
They don't come out in a hamper, just the plastic tub they are stored in.
I keep saying I will do an advent wreath as well, but never get around to it so the candles are still unused 6 years after I bought them.
DD usually needs things like tinsel to decorate her boat for the last training day of the season in mid-December, and tacky/festive hair clips or jewellery for various parties/last matches/end of school events etc. So an old Christmas pudding shaped hat and a snowman scarf and candy cane decorated sports socks are usually rooted out again for those types of things as they come up.
We don't usually put the tree up until later in the month - about 2 or 3 weekends before Christmas itself. Some years, I will put up DD's santa "spinner" or some window clings in her room. But it only slowly creeps into the rest of the house - maybe some paper chains that DD has made, cards we receive on the mantle, the crib on the hall table, and maybe some bits and pieces (another snowglobe, some more Christmassy mugs etc) appearing in the kitchen.
There are some things that literally only come out the weekend before Christmas - a couple of festive handtowels I got as gifts years ago, my little cream jug and a serving plate, Christmas scented oil in the burner or a festive yankee candle.
And new PJs (whether festive designed or plain) and the Christmas candle and the old family copy of "Twas the Night before Christmas" only arrive on Christmas Eve itself.
