I just wanted to show once more how beautiful embroidery on paper and cardboard can be ;-)
Here I cut a beautiful blue patterned square from a magazine and glued on white cardboard.
Then I drew very faint curved lines with a pencil, pricked holes along the lines and stitched them with a chain stitch.
Looks fine, doesn’t it?
I find though that the chain stitch looks much better on straight lines or wide curves than on sharp turns (it ‘inclines’ somewhat), that’s something one could pay attention to when drawing the lines.

After the embroidery I put the orange peel between several layers of tissue paper in an old telephon book and let it dry ‘flat’.
I find worst that the threads now stand up now like croquet wickets, I really don’t like this.
On the picture you see a little ‘piece of art’ that was meant originally as a card but is much to time-consuming for this: it is a Clematis petal pressed in an old phone book, embellished with self-made decorative paper and hand embroidery.
Here I’ve pressed a leek leaf in an old phone book, too, and embroidered it.
I don’t know what kind of leaf this is, but I combined it with self-made decorative paper, self-made 
The pattern shows inside, too.
