Got this idea from seeing some gals at Bible study use these rings to keep notecards with verses together...
Originally, I thought I'd put Liv's baby shower and birthday cards in her baby book, but now I can put them in a memory box for her to comb through someday--I like how all of the cards are corralled, but easy to flip through (vs. just using a rubber band or something).
I did the same for R's 30th birthday cards as he has a drawer he keeps mementos in. Sweet.
Punch. Click. Done!
