Decide on your image size and its placement on the canvas and then trace over it, placing the carbon copy paper between the canvas and the image. Make sure the carbon copy paper is the right way round or it will not work.
If you don't have an image or carbon copy paper, you can hand-draw the image you want.
Thread the embroidery thread through the needle. Stitch through the canvas, following the lines you transferred onto or drew on the canvas. Keep stitching until your embroidered canvas art is done.
I found that two strands from the thread, doubled over (to effectively be four) were sufficient for this project.If you want your background in a different colour, simply paint the background before drawing or tracing on your image.
