Round Cactus Crochet Keychain Pattern

This round cactus crochet keychain is a compact amigurumi project with a simple rounded shape, subtle embroidered cactus spine details, and a crocheted hanging loop for attaching keychain hardware.

The cactus body is worked in continuous rounds from the bottom up, then stuffed and shaped before the opening is closed. A separate crocheted loop is securely sewn to the top, making the finished piece ready to pair with a keyring or other suitable hardware.

Before You Start

Work in Continuous Rounds

The cactus body is worked in continuous rounds rather than joined rounds. A stitch marker can help you keep track of the first stitch of each round.

Count Your Stitches

Keep the stitch count consistent as you work. The body gradually increases to 36 stitches, remains at 36 stitches through the middle section, and then decreases toward the top opening.

Stuff as You Go

Begin adding fiberfill during the decrease section. Add small amounts at a time so the cactus stays rounded without becoming overly firm.

Shape Before Closing

Before finishing the final rounds, check the shape from several angles and adjust the stuffing as needed.

Construction Order

The project is completed in this order:

Crochet the cactus body.
Stuff and close the body.
Make the hanging loop.
Sew the loop to the top.
Add the embroidered cactus spine details.
Attach the keyring hardware.

Round 17

6 dec. (6)

Fasten off, leaving a yarn tail. Use a tapestry needle to close the remaining opening and weave in the end securely.

Make the Hanging Loop

Using green yarn, chain 14.

Fasten off, leaving a long tail for sewing.

Fold the chain into a loop and position both ends together at the top center of the cactus. Sew the two ends securely across several stitches so the loop has a stable attachment point.

Before trimming the yarn, check that the loop is centered and positioned to support the keyring without pulling on a single stitch.

Add the Cactus Spine Details

Thread the cream or off-white yarn onto your tapestry needle.

Add several short embroidered marks around the cactus body to suggest cactus spines. Keep them small and distribute them around the visible surface for a balanced look.

Avoid placing the embroidery directly over the hanging-loop attachment.

Because these details are decorative, their exact spacing can be adjusted visually to suit your finished cactus.

Assembly

Step 1: Finish the Cactus Body

Make sure the cactus is completely stuffed, the final opening is closed, and all loose ends are secured.

Step 2: Attach the Hanging Loop

Center the crocheted loop at the top of the cactus and sew both ends securely across several stitches.

Step 3: Add the Decorative Details

Complete the embroidered cactus spine details if you have not already done so.

Step 4: Attach the Keyring

Pass the keyring through the crocheted hanging loop.

Step 5: Check the Finished Shape

Make sure the cactus remains rounded, the loop is centered, and the keyring attachment feels secure before using the finished piece.

Finishing

Weave in any remaining yarn ends.
Trim excess yarn neatly.
Check that no stuffing is visible through the stitches.
Make sure the hanging loop is firmly attached.
Adjust the cactus shape gently before the final use.

Helpful Tips

Keep the stuffing even

Add fiberfill gradually rather than packing the body all at once. This makes it easier to maintain an even, rounded shape.

Check your stitch count

If your count is off at the end of a round, correct it before continuing. The shaping depends on the stitch counts remaining consistent.

Shape before closing

Small adjustments to the stuffing can make a noticeable difference in the finished silhouette, especially during the final decrease rounds.

Center the loop

Take a moment to check the loop from the front and back before sewing it permanently into place.

Keep the embroidery balanced

Use the finished cactus itself as your guide for placing the spine details rather than relying on rigid measurements.

Troubleshooting

My cactus looks too flat

Check the amount and distribution of stuffing. Add small amounts gradually and shape the body as you work.

The stitches look stretched

The body may be overstuffed. Remove a small amount of filling and reshape the cactus.

The top does not close neatly

Check that the decrease rounds have the correct stitch counts and that the final opening has not been overfilled.

The hanging loop feels unstable

Reinforce both ends of the loop by sewing across several stitches rather than anchoring the loop to only one stitch.

The cactus spine details look uneven

Because the embroidery is decorative, you can reposition the marks to create a more balanced appearance before fully securing the yarn.

Customization Ideas

Change the cactus color

Use a different green shade or another color that suits your preferred style.

Change the spine color

Cream or off-white creates a subtle contrast, while another contrasting yarn color can create a bolder look.

Try a different size

Changing yarn weight and hook size can alter the finished size, although the result will depend on tension and materials.

Use it as a bag charm

The crocheted hanging loop can also be paired with suitable bag hardware instead of a traditional keyring.
