An airy lace shawl that can be extended infinitely to the size you wish.
The outcome will be a longer winged triangle, comfortable to use as a scarf as well.
The pattern of the shawl is written in detail, and has a clear chart as well. 5 rows are repeated.

Gauge is not critical.
For the yarn I used Red Heart Unforgettable, I used a 6 mm crochet hook to achieve an airy feeling.
One skein was enough for a medium size shawl.
