Materials and Preparation for Kofy Hat
📌 The tutorial requires a weight 2 yarn (fine/sport), specifically a 100% cotton yarn resembling dishcloth material, with a weight of $50\text{g}$ ($1.8\text{oz}$) and $165\text{m}$ ($180\text{yd}$).
✂️ Recommended hook size is $3\text{mm}$ ($D\text{US}$), but the creator uses a slightly larger $3.5\text{mm}$ ($E\text{US}$) due to tight tension.
🧺 Washing Instructions: Machine wash gently in lukewarm water; never use bleach or softener; tumble dry delicate or dry flat in the shade; do not wring the finished item.
🛠️ Essential tools include the yarn, crochet hook, scissors, a darning/tapestry needle, and a stitch marker.

Crochet Pattern: Initial Rounds (Increasing the Circle Base)
🔄 Start with a magic ring (or magic circle) and chain one.
🔷 Round 1: Place 12 half double crochets (hdc) into the magic ring, marking the first stitch.
➕ Round 2 (Increase): Chain one, place 2 hdc in the starting stitch (move marker), and then place 2 hdc in every stitch around, ending with 24 stitches.
🔁 Round 3 (Increase Pattern 1, 2): Chain one, place 1 hdc in the first stitch, 2 hdc in the second stitch, and repeat the $(1\text{hdc}, 2\text{hdc})$ pattern around, ending with 36 stitches.
🔢 Subsequent Rounds (Increasing by 12 Stitches): Each subsequent round increases the number of single hdc stitches between the double hdc increases by one (e.g., Round 4 is $1, 1, 2$; Round 5 is $1, 1, 1, 2$), with the stitch count increasing by 12 per round ($48, 60, 72, 84$ stitches).

Sizing and Transition to Body Section
📏 Sizing Approximation: Stopping after 5 rounds yields a circle diameter of approximately $4.75\text{ inches}$ (less than $12\text{ cm}$), suitable for a small size Kofy hat.
🧶 Medium Size: Increase one more round (Round 6) to reach 72 stitches.
🔥 Large Size: Increase two more rounds (Round 7) to reach 84 stitches.
➡️ The final increase round before starting the body section determines the base circumference.

Crochet Pattern: Creating the Ribbed/Textured Body Section (Rounds 6-8 for Small Size)
🔄 After the final increase round, slip stitch, chain one, and prepare for the body section pattern, which alternates between two stitch types for 8 total rounds in this section (3 initial rounds followed by repeating two alternating rounds).
🔹 First Body Round (e.g., Small Round 6): Use double crochet (dc). The pattern is $1\text{ dc}$ in the first $N-2$ stitches, followed by $2\text{ dc}$ in the final stitch (e.g., for Small: $1\text{ dc}$ in the first 9 stitches, $2\text{ dc}$ in the 10th stitch).
🔗 Second Body Round (e.g., Small Round 7): Starts with a front post double crochet ($\text{FPdc}$) around the first stitch, followed by chain one ($\text{ch} 1$), skip one stitch, and $\text{FPdc}$ around the next post, repeating ($\text{FPdc}$, $\text{ch} 1$, skip 1) pattern.
🧱 Third Body Round (e.g., Small Round 8 - Solid Round): Work a regular double crochet ($\text{dc}$) into the $\text{ch} 1$ spaces and $\text{FPdc}$ around the previous posts, creating a solid round with no gaps.
🔁 Repeat the pattern of the second and third body rounds ($\text{FPdc}/\text{ch} 1$ round alternating with the $\text{dc}/\text{FPdc}$ solid round) until a total of 8 rounds are completed for this section, or continue for a deeper hat, ensuring the section ends on a solid round.

Finishing the Brim with Unique Single Crochets
🛑 Brim Preparation: After the body section, complete 3 rounds of single crochet ($\text{sc}$).
1️⃣ First $\text{sc}$ Round: Place $1\text{ sc}$ in every stitch around, marking the first stitch.
✨ Second and Third $\text{sc}$ Rounds (Unique Technique): Instead of inserting the hook under the top two loops (slicing the icing), insert the hook into the center/heart of the body of the previous round's $\text{sc}$. This creates a braided or linked chain effect. Be consistent in using this technique for both the second and third single crochet rounds.
✂️ After the final round, slip stitch, chain one, cut yarn, and weave in ends securely, utilizing the starting tail to close the magic circle hole tightly.

Key Points & Insights
➡️ Use 100% cotton yarn for the Kofy hat structure, similar to dishcloth material, and adhere to no bleach/no softener washing instructions.
➡️ The foundation is built on rounds that consistently increase the stitch count by 12 per round based on the round number ($N \times 12$ stitches for round $N$ in the base).
➡️ For the unique brim effect, insert the hook into the center of the single crochet body rather than the top loops for the final two rounds.
➡️ The creator advises fitting the flat circle base to the crown of the wearer's head for the best fit rather than strictly relying on round counts for sizing.
