I was inspired by Maxine’s beautiful shawl.

Edge
For the edge, I tried Ragamuffin’s idea, then Knitterlee’s, and finally AcorntoOak’s. I chose the latter but I replaced the picots with two chain stitches and I slightly changed the center part.

I ended with an odd row of the repeat (I had twelve grams of yarn left to finish it off).
(ch4, dc, ch1, dc, ch1, dc, ch2, dc, ch1, dc, ch1, dc) in the ch3 space of the previous row
sc in the 2nd dc of the three dc of the previous row
(dc, ch1, dc, ch1, dc, ch2, dc, ch1, dc, ch1, dc) in the ch3 space of the previous row repeat
For the center,
(dc, ch, dc, ch, dc, ch, dc) in the ch3 space of the previous row, (ch, dc, ch3, dc, ch) in the dc in the middle of the previous row, then (dc, ch, dc, ch, dc, ch, dc)
On the straight edge, I did a row of single crochet stitches (3sc in the ch3 space, 2sc on a dc) , followed by crab stitches (reverse single crochet) like Maxine on her other beautiful shawl.

Only one gram left at the end that I used to create a croco-flower with only five petals (ch5 instead of ch7 at the beginning). This flower will be used to decorate the pin that will close the shawlette.

1 skein: 70cm*33cm (nearly 27 rows).
2 skeins: 100cm*45cm (38 rows).
3 skeins: unblocked 125cm*60cm (45 rows),
after wash when wet 135cm*70cm,
after being blocked 136 cm*71cm

I am not so sure I succeeded my blocking (it was my first one) as the size of the shawlette is quite the same just after the wash and after the blocking; I have been interrupted in its process for three hours, thus the yarn was not so wet. But I am happy with the result as the lace opened up. I really like this pattern, the edge (thanks AcornToOak) and the crab stitch straight edge (thanks Maxine).

BTW, this page about blocking is worth reading.
