I have written instructions and charted instructions included in this pattern as seemed useful to me:
-The flower rows are only in chart form. I think it is best communicated this way.
-The top section is charted as well as written out, so you have your choice.
-The last section which is the long wavy edge is written only. There is no paper big enough to chart this part.

Besides knowing basic stitches, including chain, single crochet, double crochet, adjustable loop, decrease double crochet 3 together, and 3 treble crochet cluster (also called treble crochet 3 together), you will need to master, if you haven’t already, the “Y” stitch, which proves so useful for the flower stems. The “Y” stitch is done by first making a double treble, then poking back into a strand found in the middle of its length and working 2 dc there. I have made a video tutorial for this Y stitch, which you may see here.

The biggest challenges of this project are that you have to work double crochets into chain stitches rather than over the chain space for the main part of the shawl, and also you have to keep count at least on alternate rows. The increases are spread throughout the solid rows to create the curve, and the stitch count will matter once you get to the flower insert.

I used 2 skeins of the main color for this shawl and only small amounts of the other 2 colors; less than 20 yards of the yellow, and less than 25 yards of the green.

I loved how the Folio yarn worked for this project, which is classified as DK weight. However, if you want to use another yarn, most DKs will seem heavier and less drapey than the Folio. So if you want to substitute, I would recommend going to a lighter weight such as a sock yarn.

It measures about 40” across the top straight edge.
