🧶 Materials and Preparation: What You’ll Need

THE BEST CROCHET PATTERN

Before starting your crochet fish keychains, it’s important to prepare your materials. Keeping your workspace organized helps you stay focused and enjoy the process.

1. Yarn Choices
   For this project, use cotton or acrylic crochet yarn in various bright colors. Worsted weight (category 4) yarn works best to give the fish structure. You’ll need around 10-15g per fish.

2. Recommended Hook Size
   Use a 3.0 mm to 4.0 mm crochet hook. The smaller the hook, the tighter and cleaner the stitches — perfect for keychains.

3. Other Notions

   • Keychain rings or lobster clasps

   • Yarn needle for weaving ends

   • Scissors

   • Small amount of stuffing (polyfill or yarn scraps)

   • Safety eyes (6mm or embroidered)

4. Stitch Knowledge
   This crochet pattern uses basic stitches:

   • Chain (ch)

   • Single crochet (sc)

   • Slip stitch (sl st)

   • Increase (inc = 2 sc in one stitch)

   • Decrease (dec = single crochet two together)

5. Cutting Measurements for Felt (Optional)
   If you want to add small felt fins, cut two side fins and one top fin using these sizes:

   • Side fins: 1″ x 0.75″

   • Top fin: 1.5″ x 1″
     Use scissors and felt in coordinating or contrasting colors.

6. Work Environment
   Set up a bright, comfortable space with your tools at hand. Since the project is small, it’s perfect for crafting on the go or while watching your favorite series.

🐠 Step-by-Step Crochet Pattern for the Fish Body

Let’s start with the core of your crochet fish keychain — the body. You’ll work in rounds to shape it and lightly stuff it for a squishy, plush feel.

   • Embroider a smile or add stripes using surface slip stitches.

   • Use contrasting yarn for visual pop.

🎣 Finishing Touches and Keychain Assembly

You’ve completed the main fish! Now it’s time to convert it into a fun and functional keychain using a few quick steps.

1. Attach the Keychain Ring

   • Use a small jump ring, lobster clasp, or metal chain.

   • Sew or crochet a short chain loop (ch 6, sl st back) at the top of the fish.

   • Slide the metal ring through the loop and close it.

2. Secure All Pieces

   • Double-check all fins, eyes, and tails are firmly attached.

   • Tug gently to test the durability — remember this will be handled a lot!

3. Decorate (Optional)

   • Add beads or small charms near the keyring.

   • You can also sew initials onto the fish or add felt heart appliqués.

4. Personalize Colors

   • Use ombré yarn or variegated threads for a more dynamic look.

   • Make themed versions like rainbow fish, metallic scales, or neon colors.

5. Gift-Wrapping Ideas

   • Place in a clear plastic bag with a ribbon and handmade tag.

   • Great for party favors, stocking stuffers, or birthday gifts.

6. Care Instructions

   • Spot clean only with a damp cloth.

   • Do not machine wash. Store in a dry area.

🧵 Custom Variations and Creative Extensions

Once you’ve mastered the base crochet pattern, you can easily adapt it to make other aquatic or animal-themed keychains.

1. Make a Whale Keychain

   • Elongate the fish body and add a horizontal tail.

   • Use white yarn on the bottom for a whale belly.

2. Turn It Into a Mini Plushie

   • Increase stitch counts and make larger versions.

   • Add a loop for hanging instead of a keychain ring.

3. Design a Whole School of Fish

   • Make different color combinations to represent a rainbow school.

   • Display in a hanging mobile or window string decor.

4. Add Texture With Puff Stitches

   • Use bobble or puff stitches for scales on the fish body.

   • Alternate with smooth sc rows for contrast.

5. Make a Matching Coin Pouch

   • Sew a zipper to the top of a larger fish body.

   • Add lining fabric inside using felt or cotton.

6. Sell or Share Your Work
