Last week I ran a craft day making projects using the envelope punch board. This is a gift box that we made that holds up to 6 cards.
I have used the Natural Composition Speciality designer paper for this box. it makes a nice sturdy box. Instead of putting velcro or a fastener round it I have made a belly band that slides off.
This box fits standard 6 x 4 cards in it.
Thanks Marilyn for the measurements.
