If you have lots of photos from baby's first year, these are the perfect first birthday invitations to send! Our unique five-panel format holds an amazing twelve photos inside, plus one on the front, yet somehow manages to fold up to a petite 4-7/8 x 3-1/2" size for mailing. The front panel announces the big birthday event, in your choice of colors, with a photo of the happy one-year old. The birthday invitations open vertically, accordion style, to show nine more photos in snapshot style frames scattered below. Three more photos fit on the back, with editable text for your party details. Choose your favorite colors for the text, monster and yellow background. It's easy to personalize these 1st birthday invitations by uploading your favorite photos and simply dropping them into place. Switch colors instantly to find the look you love, or try different color combinations all day long. Add party details and, that's it, you're done!
