I don't do Christmas but I am not a Scrooge so here is an easy to make decoration. I think it may have been on the old forum but can't actually remember where I got it.
Cut out a circle from 2 contrasting fabrics - I used a tea plate to draw round.
Put them right sides together and stitch a 1/4" seam all round leaving a small opening to turn through. Make some notches in the seam allowance so that it is not lumpy when turned right sides out.
Turn right sides out and (this is the only fiddly bit) use the point of a needle or pin to pull out the seam edges so that you get a nice neat circle. Topstitch all around the edge closing up the gap as you go.
Fold in half vertically and mark the north and south points with pins. Repeat for the east and west points.
Use a needle and thread to first catch the north and south points together then, without breaking the thread, catch the east and west points together. Leave the thread end if you want to attach an embellishment in the centre.
Fold back each of the 4 'petals' - give them a bit of a push and wiggle to get them looking nice. Add a decoration if you want one and a hanging loop.
