You don't need to get hung up on buying ready-made garlands and baubles - half of the New Year magic comes from stuff you already have at home. Cut out snowflakes from paper, hang them on strings, make a garland from newspapers or magazines, scatter candles (even regular tea lights) around shelves and tables - it instantly feels festive. If you've got branches from outside, put them in a vase, wrap them with white string, add tinsel or even just tie on paper stars - it looks expensive but costs next to nothing. LED garlands are sold in any hypermarket now for dirt cheap, that's the main thing worth buying, everything else comes from your imagination.
