Well, not all the blank parts shown written on the example should be filled, for instance the blue ribbons can be left blank if you wish. The RSVP part could also be left empty or filled with another details (dress code?).
It's your party, anyway, so have fun and fill those blanks as you'd wish. Don't forget, I won't mind a few DIY alteration and creative embellishment, send us a photo of your creations! But please remember to use the file for PERSONAL USE only, and if your friends ask for it, give them the link, not your copy :) . Have fun inviting!
