This is a 3x3 box template originally from the Scrapbook Lounge ( chocolate box episode Dec 2008 ) I've resized it so it will print out the right size for 3x3 notecards and envelopes.
The dotted lines are erased so that it can be printed directly on cardstock, but that does mean you may want to consult the original template for where to score (Please note it is
not resized but attached here as a score guide)
The Deets:
It measures just over 3 2/8" square & 1 1/2" deep
It has a cute little lid and
It holds 15 or more 3x3 notes
