I bought one of those quilt planners a few years ago but didn't use it. I didn't need the information it had boxes for, but I needed other information - sizes of parts of quilts, the finished size, when I started/finished, etc. So I just got a spiral notebook and have been very happily using that ever since. I take photos that live on my phone or computer - just uploaded the phone photos to the computer after 5 years! Do what works for you, not for the designers.
