Our Baking invitation is printed on 5.5" X 4.25" white card stock. As a special feature we allow you to order by the piece (1 card + 1 envelope) so you can order any amount you wish– reorders are easy too! We send out e-mail proofs of all of our invites and the final version is not printed without an approval email from you. Any questions? Need help with the wording? Please don’t hesitate to email us ...firstname.lastname@example.org or call us at 516.610.0181.
