To make your wedding invitations more special, funny and cool, make an envelope liner! It’s simple, free and won’t take much time or any special skills! The supplies are simple: a paper cutter or scissors, templates, double-sided stick tape or glue stick, envelopes. Print off your template pattern and cut off the white edges. Measure the size of your envelope and cut about 1/16″ smaller to the shape. Put down the tape and secure the liner to the tape. Crease the liner to the crease of the envelope. Put your invitation inside and make a great impression on your guests!
