Creating a sketch from a photograph

It would be really nice if there was an easy way of creating a line drawing from a photograph. I have downloaded filters, used various filters in Photoshop and have tried many stand alone programs that aim to create line drawings.
Here is my photograph.

an here is the line drawing from the best of the downloaded programs I have tried - this one called "Fotosketcher"

The results are not brilliant - the colour sketch was impressive but was not the line drawing I was after.
So, I resolved to create a sketch that I could give to my grandchildren to colour-in.

 This is the sketch that I made from the photograph.
Here are the steps I took to do that.
To begin with I created a blank layer above the original photograph. (Ctrl+J in Photoshop  Elements)
With a smooth edged brush and a contrasting RED as the foreground colour I zoomed in on the picture and started to draw around the edges of the horses.

Using red it is so much easier to see where I had been - I started out using black but soon gave up because the black was lost in the black areas of the shadows.
I use a graphic tablet so drawing around the horses was not as difficult as if I were using my track-ball mouse. I soon found that I could start the line exactly where I wanted it to start with no hovering about to see where the cursor was. The secret is to zoom in very close.
Once the outlines and harness details had been drawn I then clicked on the background and filled it with white. (Edit>Fill Layer>White )

I found that I had missed out the detail of the bit on the white horse so had to click "Undo" to remove the white and fix the problem. Once done I could fill the background with white once again.
Of course I did not want a red sketch, I wanted a black and right sketch.
I clicked on Layer 1 - the red sketch - and from the Menu bar clicked on Enhance>Convert to Black and White.

There are a few options to choose from - I found "Portrait" to give me the blackest lines.
The very last thing I did was again to go to the Menu Bar, click on Layers>Flatten image.
So now I feel I know how to create my sketches without the use of filters or special programs! DIY.
