I just made a king size one. The only trouble I had was in laying it out. I have a queen size bed and didn't have any space big enough to lay it out. In the front of the book she has a chart telling you how many of each block you need for whatever size you are making. I also put sample blocks on a sheet of paper and pined it in front of my cutting mat. That helped me a lot. Good luck with your lover's knot.
