Over a couple of days it christmas and when you look in your home and there's something missing for decoration with this tip you make very easy a lovely decoration.
Take a canvas (10"x10"), paint, shape of a christmas tree and some buttons.
Paint the canvas with colour of paint you like. Draw your christmas tree on canvas. Take your buttons sew them around your christmas tree. And there you have your tree of buttons.
And other way is cross stitch around the shape of the tree.
Very easy to do and a lovely decoration.
Have fun with it.
