Here's a pretty decoration from the Paton's Traditional Christmas family front room - a knitted Christmas tree bauble that you could make to co-ordinate with your decor, or Christmas jumpers.
I like these a lot, but won't be making them as the cats will think they are special cat toys and destroy the tree.
Yarn: Use oddments of DK.
Needles: 3 3/4 mm needles.
Tension: 24sts and 32 rows to 10cm in stocking stitch (although let's lighten up here a minute - these are Christmas tree baubles, they don't have to be precisely the same size as the pattern)
With main colour cast on 5 sts and purl 1 row.
