Cast on 43 air loops (VP) - 2 * 18 for rapport, 7 for symmetry and 3 for lifting (R).
First row: work a double crochet (dc) into the fourth warp stitch. Pass 2 loops, and through the third make a group of 3 dc (dc). After completing 3 GR with the same passes, dial 13 VP. Skip 5 warp loops and knit a GR in every third loop - 5 times in total. Knit 13 VP again and continue in the same way, completing the row will be 2 dc and p. Follow the alternation of the pattern along the edges of the fabric: above a single p after the GR of the previous row there should be 2 dc or dc and p and vice versa.
Second row: 4 GR between the GR of the first row and a chain of 6 VP (C). The hook can be inserted into the arch itself between the GR or inside the loop connecting 2 GR to slightly vary the pattern of the canvas. Knit a single crochet (SC) through the middle of the chain from the VP (here you can also insert the hook into the loop itself or under it), C and again perform 4 GR between the GR of the first row. Repeat this until the end and make a dc through the lifting loops of the first row and P.
Third row: duplicate the outer dc. Knit 2 GR and C.Next, 3 RLS: near the attachment of the first D to the RLS of the second row, but not through the RLS itself, another above the RLS itself and again over the edge of the next D. Then again a D, etc. Complete row 2 Dc and P.
Fourth row: 2 GR, C and 5 RLS: 2 behind the C on both sides and 3 across the RLS of the third row. Type C and repeat the pattern. At the end of CH and P.
Fifth row: Repeat dc. Knit GR, C and 7 RLS, increase RLS as in the fourth row. Continue symmetrically until the end, then make 2 dc and p.
Sixth row: perform a GR in the arch above the GR and another one through the beginning of the T. Make a T and 5 RLS, skipping the outermost RLS of the fifth row.
The seventh row repeats the third, the eighth and ninth are knitted similarly to the second and first.
