Parchment

True parchment is made from carefully processing animal skins (using some pretty awful 'stuff' along the way) to yield a soft but durable surface that has a creamy colouring. It was used extensively through the Middle Ages for manuscripts. 

DMC approximation is 3866 on both linen and evenweave. 

This colour works well on all available fabrics, with linen giving the brightest results. Lugana, other evenweaves and Aida give paler (more muted) results.
