One Christmas decoration I do like making is a string of hearts, separated by crystal beads that sparkle in the light. These were made for someone with a black and white themed room. My own Christmas theme is more the 'all bar(including?) the kitchen sink' theme.The hearts were very simple to make.
I just drew round the heart template onto the back of a piece of fabric. Placed it right sides together with a second piece and stitched just inside the drawn line, leaving an unstitched section in one straight edge for filling. Then cut the heart out about 3/8 inch(1cm) outside the drawn line. Turned it right sides out, filled it with toy filling and sewed the gap closed. To add the beads I fastened the thread onto one heart, threaded five beads onto it and then joined on the next heart and fastened off.
