A new invitation idea has just been added to the website; Invitations with a shaped border. This idea is a layered invitation, where one of the layers is printed with wording. One of the cards is cut in a "shapely" manner.
This invitation idea can be made with a variety of card stock options. Get the bottom layer made out of a metallic, patterned, or textured paper. Because of that variety, pricing can vary quite a bit. A good estimate would be about $3 per set, layered invitation card, response card, and envelopes included.
*Estimated are just an average price range valid only at the time it is written. Due to inflation, pricing goes up over time.
