Book Tutorial at Oh Hello Friend

I'm guesting once again at Oh Hello Friend :)
I composed a tutorial about making these little books.

Here are a few notes after making a bunch of these:
for the spine, lighter, more flexible materials than the cardboard are better.
Things like grosgrain ribbon, lighter weight cardstock, or smooth text weight paper move and flex with the pages.
A couple other things: be sure the pages are aligned perfectly, this is the moment to be finicky. I ran into trouble with pages falling out because they were uneven.
Secondly, be sure to use enough glue on the spine. I had one notebook split along the spine because I didn't have enough glue along the edge of all of the pages.
I tried to be extremely precise with all of the measurements.
On this project, uneven edges show.
I'm still learning about book binding and look forward to trying more styles. :)
