A device useful in the formation of handcrafted envelopes comprises a board (10) with a planar surface (11) wherein the planar surface is provided with at least one guide means (12), and at least one abutting surface (13) that allows an envelope material such as paper or card to be positioned on the planar surface at a defined angle with respect to the guide means such that the paper or card can be folded to the guide means to form an envelope.
