As somebody who is out of work and has a disabled household member, buying these expensive programs is out of the question. Most people do not have a few thousand lying around.
What I personally have done is:
1) scan in patterns. I do this by taping it to taped together 8.5" x 11" papers then scanning them, making sure to overlap sections. I scan at 600 dpi personally.
2) open files in photoshop. Using the multiply setting, I put each piece together like a puzzle.
3) Using the pen tool (you do NOT need a new version of photoshop for this, older ones are cheaper as long as they have pen tool), I trace the lines of each pattern piece and then, with a 5pt brush, I "stroke" the lines. This creates the lines. If you have graded by hand, you can also do dashed lines, etc.
4) After doing this for all pieces of the pattern, I put them into one big image. I arrange them so they are all their own layer.
5) I created a "pattern" in photoshop so that it sets a grid over my work. This rectangle grid must be smaller than 8.5" x 11" (I think I use 6" x 9" but I'd have to check). I put a symbol at every line where the patterns connect. I use a heart and then put "A" on both sides (so 2 As), then B on the next line and so on (so they can connect pieces after printing).
6) I make sure everything is aligned logically on the grid. I then combine the layers (not the top grid layer though) and cut each of the pieces in each rectangle and put it in a new document. This new document has one rectangle, which is the size of the grid rectangles and I paste the image into this rectangle along with the page number in the bottom corner.
7) I make instructions in Word.
8) I combine all Pattern pages into one PDF and instructions into another PDF (to make it easier to print just patterns)
It's a bit time consuming but a cheaper option than everything else. Older copies of photoshop are cheaper and I feel the result is much nicer than using Word or just hand drawing and scanning. It's a good medium. I read multiple blogs on these techniques, finding the Burda one being best, before settling on how I did mine. If anybody wants an example of how I did mine, I have a very simple free pattern at:

GL everybody who is starting out! Just remember, read everything you can then devise the way that is best for you and your skill set...and your wallet.
Anyone can convo me if they have questions about my technique. I believe sharing is caring :)
