I covered the boards with hand-made paper of a colour similar in tone to that of the beads. I then cut the doily down to the right size and carefully pasted it down onto the front board. After gluing the boards to the leather spine I strengthened the bond with rivets.
I am mostly happy with the result, but I think it needs something to brighten it up, possibly some splashes of colour on the doily.
I think I will make another one - in pink.
