If you want to you can try and draw images with various tools on an app called Sketch. I used an ellipse tool and a symmetry tool to centre this drawing and guide the curves in it. I used leaf shapes and flowers shapes adjusted to different sizes and other pattern tools like stars for a bit of digital glitter. I used a spray gun tool to add shade, using the ellipse and symmetry to get the shadows under the leaves, then added a darker layer of leaves. I added a bow shape with a marker pen tool. Finally I added a circle around the wreath drawing to add a bit of definition and added Merry Christmas on top. I did this twice, first with a darker colour then white, slightly offsetting them to get a shadowed effect.
