Crane's Cover is a 100% cotton paper.

Although we can produce cards in any size
that you would like, it is best to match your
card sizes to the available envelope sizes.

Lettra envelopes are used with Crane's Cover.
Most Lettra envelopes have a square flap.
Both the A7 and Marquis sizes are available
in square flaps and in pointed flaps.
The pointed flap envelopes are manufactured
with inner and 1/4" oversize outer envelopes.
