I will say right away that almost all 8 skeins were used for the cardigan. Just a little bit is left.
The very first thing is the calculations that I made for myself, or rather, the distribution of the starting edge. I have already gotten into the habit of crocheting the starting edge from cells according to this scheme:

3 chain stitches, a double crochet in the first, again 3 chain stitches, a puff stitch in the first of them, and so on.

I made a total of 21 such cells.
Next, you need to crochet the first preparatory row, distributing the cells. The cells for the raglan lines are highlighted in green:

Next, we chain 3 stitches and crochet double crochets in such a way that there is an odd number of double crochets on each side. The number on the front panels will be even. At the beginning of the row, the first 3 chain stitches count as a double crochet, and at the end of the row, we will add one more double crochet for symmetry. These additional double crochets will serve as a base when edging the finished product. So.
- Front panel A — 3 chain stitches, 4, 3, 4 double crochets.
- Raglan line (2 chain stitches, puff stitch, 2 chain stitches, puff stitch, 2 chain stitches)
- Shoulder A — 3, 1 between cells, 3 double crochets.
- Raglan line.
- Back — 4, 3, 4, 3, 4, 3, 4 double crochets.
- Raglan line.
- Shoulder B — 3 double crochets, 1 between cells, 3 double crochets.
- Raglan line.
- Front panel B — 4, 3, 4 double crochets, 1 double crochet at the end of the chain.
The next row is also crocheted with double crochets, making increases of 1 double crochet before and after the raglan line. And then the dragonflies begin. The increases in all rows are the same. You will need to keep an eye on the dragonflies that do not fit entirely. Make sure that the number of double crochets on each side increases by 2.
