In the first beret (little purple) I made one more row in the increasing section and four more rows in the straight section. I used 4mm needles in the hole work. As it was a little big for an adult person I made some chages for the second beret (brown) and used 5mm needles. My adaptation to the pattern is the following:

With 4mm circular needles cast on 102 sts. Place marker and join for working in the round.
Work cable pattern for 14 rounds repeating rows 1-4, ending with row 2:
R1: k6, p1, k6, p4.
R2: 4-sl LC, k2, p1, k2, 4-st RC, p4.
R3: k6, p1, k6, p4.
R4: k2, 4-st LC, p1, 4-st RC, k2, p4.
Change to 5mm needles and begin the increasing section as follows:
R15 (inc rnd): k6, p1, k6, p2, m1 (ktbl), p2. (108 sts)
R16: * k2, 4-st LC, p1, 4-st RC, k2, p2, k1tbl, p2.
R17 (inc rnd):k6, p1, k6, p2, m1 (ptbl), k1tbl, m1 (ptbl), p2. (120 sts)
R18:4-sl LC, k2, p1, k2, 4-st RC, p2, p1, k1tbl, p1, p2.
R19 (inc rnd):k6, p1, k6, p2, m1 (ktbl), p1, k1tbl, p1, m1 (ktbl), p2. (132 sts)
R20: k2, 4-st LC, p1, 4-st RC, k2, p2, k1tbl, p1, k1tbl, p1, k1tbl, p2.
R21 (inc rnd):k6, p1, k6, p2, m1 (ptbl), k1tbl, p1, k1tbl, p1, k1tbl, m1 (ptbl), p2. (144 sts)
R22:4-sl LC, k2, p1, k2, 4-st RC, p2, p1, k1tbl, p1, k1tbl, p1, k1tbl, p1, p2.
R23 (inc rnd):k6, p1, k6, p2, m1 (ktbl), p1, k1tbl, p1, k1tbl, p1, k1tbl, p1, m1 (ktbl), p2. (156 sts)
R24: k2, 4-st LC, p1, 4-st RC, k2, p2, k1tbl, p1, k1tbl, p1, k1tbl, p1, k1tbl, p1, k1tbl, p2.
Then continue with de straight section as follows, repeating these four rows four times (i.e. finishing with the 40th round):
R25:k6, p1, k6, p2, k1tbl, p1, k1tbl, p1, k1tbl, p1, k1tbl, p1, k1tbl , p2 .
R26:4-sl LC, k2, p1, k2, 4-st RC, p2, k1tbl, p1, k1tbl, p1, k1tbl, p1, k1tbl, p1, k1tbl , p2 .
R27:k6, p1, k6, p2, k1tbl, p1, k1tbl, p1, k1tbl, p1, k1tbl, p1, k1tbl , p2 .
R28:k2, 4-st LC, p1, 4-st RC, k2, p2, k1tbl, p1, k1tbl, p1, k1tbl, p1, k1tbl, p1, k1tbl , p2 .
Then finish with the decreasing section:
R41:k6, p1, k6, p2, k1tbl, p1, k1tbl, p1, k1tbl, p1, k1tbl, p1, k1tbl, p2 .
R42:4-sl LC, k2, p1, k2, 4-st RC, p1, k2tog, p1, k1tbl, p1, k1tbl, p1, k1tbl, p1, k2tog, p1 . (144 sts)
R43:k6, p1, k6, p1, k1tbl, p1, k1tbl, p1, k1tbl, p1, k1tbl, p1, k1tbl, p1 .
R44:k2, 4-st LC, p1, 4-st RC, k2, p1, p2tog, k1tbl, p1, k1tbl, p1, k1tbl, p2tog, p1 . (132 sts)
R45:k1, ssk, ssk, k1, p1, k1, k2tog, k2tog, k1, p1, p1, k1tbl, p1, k1tbl, p1, k1tbl, p1, p1 . (108 sts)
R46:4-sl LC, p1, 4-st RC, p1, k2tog, p1, k1tbl, p1, k2tog, p1 . (96 sts)
R47:k4, p1, k4, p1, k1tbl, p1, k1tbl, p1, k1tbl, p1 .
R48:k4, p1, k4, p1, p2tog, k1tbl, p2tog, p1 . (84 sts)
R49:ssk, ssk, p1, k2tog, k2tog, p1, p1, k1tbl, p1, p1 . (60 sts)
R50:2-sl LC, p1, 2-st RC, p1, p3tog, p1 . (48 sts)
R51:k2, p1, k2, p1, p1, p1 .
R52:2-sl LC, p1, 2-st RC, p1, p2tog . (42 sts)
R53:k2, p1, k2, p1, p1.
R54:ssk, p1, k2tog, p1, p1 . (30 sts)
R55:k1, p1, k1, p1, p1.
R56:k1, p1, k1, p2tog . (24 sts)
R57:k1, p1.

Cut yarn, draw through remaining stitches and fasten securely in place. Weave in ends.
