I created the first weekly spread after watching your class. It was for the last week of January, and I have realized I didn't leave myself enough space based on all the things I add on a daily basis. (Apologies for the scribbles.) 

For my spread for the next month I reduced it to 3 days per page; I will wait to see if that works or if I need to change it to only 2 days per page. I enjoy the creative option with a bullet journal, plus the ability to change your layout if it doesn't work, rather than being stuck with a certain layout all year.
