I have shared this before, but remember
to sign and date your coloring pages.
I also put a few notes about something
that happened the day that I finished a page.
One book has become a bit of a journal.
Use a rotary date stamp like libraries used to use
for a fun way to date each page. These are very popular now
and are very easy to find.
Take some time each day to color, it is very relaxing.
