You can also change the size of the drawing when you do this if you want it to fit on a smaller or larger canvas.

You can do this on a desk, table, or even the floor.

If there are any large spaces without lines on the drawing, then you can hold the copy up to a window and mark those areas with a pencil before you start coloring the paper with charcoal. This way, you can more easily avoid those spots to save time and charcoal. If you don’t have a lot of charcoal, just retrace over the lines of the main shapes instead.

The charcoal will look darker after you rub it in. Try to make it all an even shade.

You could also just pour the dust into a trash bin if there is one nearby. Just be careful not to spill any charcoal on a carpet or anywhere that it might stain.

The number of pieces of tape you need will depend on the size of the drawing. Placing one every 1 in (2. 5 cm) or so will do the trick.

Try to keep your hand off the drawing as you go over the lines as much as possible so you don’t rub any excess charcoal onto the canvas.

If you see any spots that didn’t transfer well or spots that you missed, then re-tape the drawing and go over the lines with the ballpoint pen again.

The transferred lines will be very delicate at this point, so be careful not to rub them with anything or you will smudge the charcoal.

India ink is a black ink commonly used for drawing and outlining, especially for comics. You can get an India ink pen at an art supply store.

The advantage of using a digital projector is you aren’t just limited to transferring your drawings to canvas. You can find any kind of digital image to use as a reference, such as a photo, and trace the outline onto the canvas to fill in with paint.

You can adjust the distance between the canvas and the projector after you project the image to position it just right on the canvas.

Adjust the distance between the canvas and the projector if the image is really big or really small on the canvas. You can also make minor adjustments later using the projector’s zoom feature to get the size perfect.

Make any final adjustments to the size of the image after it is in focus using the zoom feature on the projector.

You can go over the lines when you are done with a fine-tipped India ink pen if you want them to be darker and more defined.
