"To customize the printable invitation, first download the free font Museo Slab and install it on your computer. Once the invitation PDF is open in Acrobat, just click on the placeholder text and type in your own. It is that easy," Lia says. "The second page of the printable is the envelope liner designed for an A6 square flap envelope. I love the red polka-dot liner with the kraft envelopes since the look coordinates with the kit. For this kit I used my pinking sheers for the zigzag edge, as it adds to the vintage style."
