Materials You Need
Gather these supplies to start:
-
Yarn: Use "Abuelita" brand 100% cotton yarn (3 mm thickness) or a similar yarn.

Colors for Square: White, Mango, Flag Green (strong green), Yellow, Chedron, Turquoise Blue (light blue), Navy Blue (dark blue), and Avocado Green (light green).

Notions: You need stitch markers, a tapestry needle for sewing, scissors, and synthetic stuffing.
Special Features
-
Intarsia/Mosaic Colorwork: The main square features intricate color changes on every stitch of every row. You carry multiple strands of yarn and switch colors to create a block-like, rainbow gradient effect, mimicking the album's artwork.
-
Continuous Color Sequence: You must maintain a precise color sequence throughout the project. Each color block in the final piece consists of three rows using the same color yarn before you switch to the next color in the sequence for that section.
-
Front-Loop Decrease (Invisible Decrease): You use the technique of decreasing by grabbing only the front loops of the next two stitches, creating a cleaner and less visible decrease line compared to a standard single crochet decrease.
-
Separate Basket Accessory: The keychain includes a small, detached basket made with Tobacco Brown yarn, which you sew onto the finished square.
Level of Difficulty
This project is rated as Advanced. The primary difficulty comes from managing up to seven different colors simultaneously, switching yarn on every stitch in the increase rounds, and constantly changing the active color based on a specific, multi-row sequence.
Tutor's Suggestions
-
Check the Size: The final keychain measures 14 cm. Be aware that using a different hook or yarn size will result in a different final size.
-
Managing Yarn Strands: When switching colors, ensure you leave a long enough tail from the inactive color in the back of your work. This prevents the previous color's loops from being pulled too tight, which can cause puckering or deformation of the piece.
-
Tighten Loose Corners: If the color changes at the corners look loose or gappy, pull the inactive yarn strand from the previous color slightly to tighten the stitch and close the space.
-
Color Sequence is Key: Pay close attention to the sequence of colors. Each color in the square should appear for exactly three rows before you switch to the next color in the sequence for that section.
-
Stuff Firmly: Stuff the square firmly with synthetic stuffing before closing it. This ensures the keychain maintains a clean, flat shape and does not look floppy.

Conclusion
You have successfully crocheted the complex and colorful "Young Forever" keychain. By mastering the intricate color changes and mosaic-style knitting, you created a unique and personalized piece of fandom art.
Tip
Use the "Yarn Knot" Trick to Manage Colors: Since you work with many colors at once, do not pull your inactive color strands too tightly. When you pick up a new color for the next stitch, gently tug the previous color strand from the back to ensure the stitch on the front is snug but not so tight that it warps the shape. This is crucial for maintaining the flat, square shape of the Amigurumi.
