Print Your Own Letterpress Invitations!
Hollander's enables you to actually learn the charm of letterpress printing of invitations, announcements, custom stationery, and other small printing needs by teaching you how to print your own using our letterpress equipment.
The cost is $115 per plate and includes the plate you will design, choice of ink colors, and all the instruction you need. It does not include stationery which must be purchased from Hollander's. We recommend our Arturo Stationery for printing, but many other papers are available to use.
For more information regarding printing options and scheduling, please contact us.
