I created some journal cards tonight and wanted to share. You can download both .png and .jpg formats of these here. The zip file includes each of the 7 days of the week cards, plus a blank rounded corner border card, and the base file I used (which does not have any particular day of the week in a different font) so you may edit it yourself. These are 4"x3" in size. Printing at 100% is perfect for Project Life.
Of course, you can use the .png files to add these as a photo overlay instead.
