It took a few nights of trial and error while watching TV. I first tried with yarn, just to get the basics. That was too hard since it was harder to match the result to the pictures in the book. When I gave up and tried again with paracord it was much easier.

My suggestion is to start with paracord, a book, and a 5.5mm crochet hook. You could use a larger hook, but I think it would be harder to insert into tight stitches. Make a length of about 20 chain stitches, then make several layers of single-stitches. Unravel, then start over again. You should be able to make even stitches within a day or so, then try making squares to a specific size.
