A few more quick cards....

 I used the embellisher machine to make some colourful, rather moody backgrounds, using mainly merino wool, with some silk and a little sparkly fibre.

Using black thread, I machine sketched some seed heads, without trying to be too exact.

I added a few small beads as stars, for just a touch more textural interest.
Then I used the glue gun to stick them on to the cards. 

Those are pearls ...

I made this watery piece a while ago. I was experimenting with layering strips of plastic resist in the wool before felting, and then cutting along those lines to reveal the middle layers of dark blue wool. I stitched pearls into the cut back sections, inspired by the beautiful poem in the Tempest:

Full fathoms five thy father lies

Of his bones are coral made
Those are pearls that were his eyes;
Nothing of him that doth fade
But doth suffer a sea-change
Into something rich and strange.
Sea-nymphs hourly ring his knell.

I thought I might hang it from a piece if driftwood I found on the Suffolk coast.

Idea: If that's "water" perhaps make a matching piece, "earth" in hot earthy colours - browns oranges, and make the cut out in a rough spriral shape. Decorate with brownish seed things - star anise etc.
