Absolutely darling is this original scrapbooking DIY birthday reminder tag board by Jaime Lyn at Crafty Scrappy Happy, to help her poor memory in celebrating the birthdays of those around her.

Best of all, she shares the how-to with us on how to make our own. What you’ll need:
the back of a frame, scrapbook paper, quote printed on vellum, a knob, a clip and tags to print birthdays and a calendars on.
Add dates to the tags as you remember them.
Just flip the tags for each month. A clever way to remind yourself of everyone’s birthday early!
