1. Materials Needed for Your Crochet Cactus Keychain
Before starting this Crochet Cactus Keychain Made with Pet Bottle Cap – TUTORIAL, gather all your supplies so you can enjoy a smooth, uninterrupted crafting session.
You’ll need a PET bottle cap—preferably a flat, standard-sized one. Clean and dry it well before use. This cap will form the base of your cactus pot.
Use worsted weight yarn in green for the cactus and brown or terracotta for the pot. You may also want white or pink yarn for decorative flowers on the top.
You’ll need a crochet hook suited to your yarn—typically a 2.5 mm to 3.5 mm hook is ideal for small amigurumi-style pieces.
Other essentials include a darning needle, scissors, polyester stuffing or scrap yarn for filling, and a keyring or lobster clasp for attaching to your keys or bag.
Optional but fun additions include tiny beads, embroidery thread for eyes or smiley faces, and glue for reinforcing attachments like the keyring.
Having everything at your fingertips will make the crafting process fun, efficient, and creative from the first stitch to the last.
2. Crocheting the Pot Around the Bottle Cap
The first part of the Crochet Cactus Keychain Made with Pet Bottle Cap – TUTORIAL focuses on turning the PET cap into a sturdy, yarn-wrapped flowerpot.
Start by creating a magic ring and working in rounds with your brown or terracotta yarn. Increase gradually to form a flat circle that matches the diameter of the bottle cap.
Once you’ve reached the right width, continue working without increases to build the sides of the pot. This forms a “sleeve” that will fit snugly around the cap.
Slide the PET bottle cap into the base and continue crocheting over it. You can add a dab of glue underneath for extra hold, but a tight crochet sleeve will typically secure it well.
Continue crocheting upwards for two or three more rounds to form the rim of the pot. You can use front-loop-only stitches to define the edge for a decorative touch.
Finish off and weave in the ends. Now you have a reusable plastic cap completely transformed into a handmade cactus pot—adorable and eco-friendly.
3. Making the Cactus and Assembling the Keychain
Now it’s time to create the cactus part of your Crochet Cactus Keychain Made with Pet Bottle Cap – TUTORIAL. This step brings the greenery and charm to the project.
Using green yarn, start with a magic ring and crochet in the round to form a small, slightly oval shape. This will represent the cactus body.
After a few increase rounds, maintain the stitch count to build height, then decrease and stuff the piece with fiberfill. Keep it firm so the cactus stands upright.
You can add decorative ridges using front-post stitches or by shaping the body with light stuffing and tight stitches. Play with texture for a realistic look.
Sew the finished cactus onto the top of the pot base. Make sure it’s centered and tightly attached, especially if you plan to use the keychain regularly.
Next, attach the keyring or clasp. You can sew it directly onto the top of the cactus or create a small chain loop to hang it from the side.
Your cactus keychain is almost ready—now it’s time to add those final touches that make it extra special and personal.
4. Personalizing and Finishing Your Crochet Cactus Keychain
This section of the Crochet Cactus Keychain Made with Pet Bottle Cap – TUTORIAL is all about adding character and details that make your keychain unique.
Crochet a small flower using white, pink, or yellow yarn and sew it onto the cactus. A simple five-petal flower can be made with a magic ring and basic stitches.
You can add a tiny face using embroidery thread—just two eyes and a smile go a long way in creating a cute and friendly cactus expression.
If you want a more playful look, use safety eyes and a small felt heart as a decoration. These elements make the keychain perfect for gifting.
For extra stability, reinforce the keyring area with a few stitches and consider using a small drop of glue. This ensures long-lasting use.
Add beads or charms if you want to decorate the keyring itself. Personal messages or initials can make your keychain even more meaningful.
With all these final touches, your crochet cactus keychain transforms into a complete, charming project you’ll be proud to carry or give away.
