Petal Loop Lanyard & Keychain Crochet Pattern Tutorial
If you’ve been looking for a crochet project that’s quick to finish, endlessly customizable, and genuinely useful in everyday life, the petal loop lanyard and keychain might just become your new favorite make. This beginner-friendly pattern combines a simple looped construction with delicate petal details to create something that looks far more complicated than it actually is. Whether you’re making it for yourself, gifting it to a friend, or selling it at a craft fair, this design hits all the right notes — charming, functional, and completely handmade.
In this tutorial, I’ll walk you through everything you need to know: the materials, the stitches, the step-by-step instructions, and tips for customizing the design to suit any style. By the end, you’ll have a finished petal loop lanyard or keychain you’ll be proud to carry everywhere.
What Is a Petal Loop Lanyard?
Before we dive into the pattern, let’s talk about what makes this style so special. A petal loop lanyard is a crocheted cord — usually worn around the neck or wrist — that features small petal-shaped embellishments worked into or along the chain. The result is a dainty, floral aesthetic that elevates a simple lanyard into something that looks almost like jewelry.
The keychain version follows the same basic construction but is worked shorter, with a key ring attached at one end. Both versions are made using the same foundational techniques, so once you learn one, the other comes naturally.
These make wonderful gifts for teachers, nurses, students, or anyone who carries keys or an ID badge on a daily basis. They’re also a great way to use up small amounts of yarn from your stash — each piece takes very little material, so you can make a whole set in multiple colorways without spending much at all.
Materials You’ll Need
One of the best things about this project is how minimal the supply list is. Here’s what you’ll need to get started:
Yarn: Size 10 crochet thread or lightweight fingering weight yarn works beautifully for this pattern. Cotton thread gives the petals a crisp, clean look, while a soft mercerized cotton blend will add a subtle sheen. You’ll need approximately 50–75 yards for a full-length lanyard and about 15–20 yards for the keychain version. This is a perfect stash-buster project.
Crochet Hook: A size 1.75mm steel hook pairs well with size 10 thread. If you’re using fingering weight yarn, try a 2.25mm or 2.5mm hook. Always check your tension before beginning and adjust as needed.
Key Ring or Lobster Clasp: For the keychain version, you’ll need a small key ring — the standard 1-inch split ring works perfectly. For a lanyard, you can use a lobster clasp with an adjustable slide or a swivel clip if you want to be able to remove it from the cord.
Scissors and Tapestry Needle: These are essentials for any crochet project. You’ll use the tapestry needle to weave in your ends neatly.
Optional: A small stitch marker can be helpful for keeping your place, especially while working the petal sections.
Abbreviations Used in This Pattern
This pattern uses US crochet terminology. Here’s a quick reference for the stitches you’ll encounter:
ch — chain
sl st — slip stitch
sc — single crochet
hdc — half double crochet
dc — double crochet
tr — treble crochet
sp — space
rep — repeat
rnd — round
Understanding the Petal Stitch
The petal detail in this pattern is created using a simple shell-and-loop technique. Each petal is formed by working a small cluster of stitches into a single chain space, which causes the fabric to cup slightly and create a flower-like shape. You don’t need any special stitch knowledge beyond the basics — if you know how to make a chain, a single crochet, and a double crochet, you have everything you need.
The petals sit naturally along the lanyard cord without adding much bulk, which means the finished piece lays flat and doesn’t get tangled easily. This is an important feature for something you’ll be wearing or carrying daily.
Gauge
Gauge is less critical for this project than it would be for something like a garment, but it’s still worth checking if you want your finished piece to match the measurements below.
With size 10 thread and a 1.75mm hook: 10 chain stitches = approximately 1 inch. Your petal sections should measure roughly ¾ inch across each.
Finished Measurements
Lanyard: Approximately 18–20 inches long (excluding the clasp), with petals spaced every 1.5 inches along the cord.
Keychain: Approximately 4–5 inches long, with 3 to 5 petals depending on your preference.
You can easily adjust the length of either version by adding or subtracting chain stitches in the base cord section.
Petal Loop Lanyard Pattern — Step by Step
Starting the Lanyard
Begin by attaching your thread to the lobster clasp or swivel clip using a slip knot. You can do this by looping the thread through the metal ring and securing it with a slip stitch before beginning your chain.
Foundation chain: Ch 15 (or as many chains as needed to create your first cord segment — roughly 1.5 inches of chain). This forms the first section of your lanyard cord.
Working the First Petal
Rnd 1 — Petal base: Ch 5. In the first ch of your 5-ch loop, work the following: sc 1, hdc 1, dc 3, hdc 1, sc 1. This creates a small, curved petal shape. Sl st into the last chain of your 15-ch base cord to anchor the petal. You now have your first petal attached to the cord.
Continuing the cord: Ch 15 again to create the next cord segment. This is the standard repeat — you’ll alternate between cord sections and petals all the way along the length of your lanyard.
Repeating the Pattern
Repeat the following sequence until your lanyard reaches the desired length:
[Ch 15 for cord segment, ch 5 for petal loop, work sc, hdc, dc 3, hdc, sc into the first ch of the petal loop, sl st into the last ch of cord segment] — repeat from until piece measures approximately 18–20 inches, or your preferred length.
Finishing the Lanyard
Once you’ve reached your desired length, ch 10 and sl st into the key ring or the second clasp end. Fasten off, leaving a 6-inch tail. Use your tapestry needle to weave the tail through several stitches, then trim. If you’d like a more polished finish, you can also work a small ring of single crochet stitches around the key ring to cover it completely before fastening off.
Petal Loop Keychain Pattern — Step by Step
The keychain version is worked using the same petal stitch, just on a much smaller scale. It’s a wonderful quick project — most crocheters can finish one in under 30 minutes once they’ve got the stitch pattern down.
Attaching to the Key Ring
Begin by looping your thread through the key ring and securing it with a slip stitch. Ch 10 to create the base of your keychain cord.
Working the Keychain
First petal: Ch 5, work sc, hdc, dc 3, hdc, sc into the first ch of the loop. Sl st into the last ch of your 10-ch cord. This anchors your first petal. Ch 10 for the next cord section.
Repeat this sequence 2 to 4 more times, depending on how long you’d like your keychain to be.
Final section: After your last petal, ch 5 and work a small ring of sc stitches to create a loop at the end. This loop can be used to attach a tassel, a charm, or simply left as a decorative detail. Sl st to close the loop, fasten off, and weave in ends.
Tips for a Beautiful Finished Piece
Keep your tension consistent. Because you’re working with fine thread, any variation in tension will be more noticeable than it would be with bulkier yarn. Try to maintain a relaxed, even grip throughout. If you tend to crochet tightly, go up a hook size.
Block your finished piece. Cotton thread responds beautifully to wet blocking. After finishing, soak your lanyard or keychain in cool water, gently squeeze out the excess, and lay it flat to dry. This evens out any uneven stitches and gives the petals a more defined shape.
Use stitch markers to track your petals. If you lose count of how many petal sections you’ve completed, a small removable stitch marker placed at the beginning of each cord segment can help you stay on track.
Leave longer tails when fastening off. It can be tricky to weave in ends on very fine thread, so leaving at least 6 inches gives you enough length to work with comfortably.
Try variegated thread for a colorful twist. A hand-dyed or self-striping size 10 thread creates a gorgeous effect along the petal sections, since each petal naturally catches different colors as the variegation changes. This is a lovely option for gift-making.
Customization Ideas
Part of what makes this pattern so appealing is how adaptable it is. Here are a few ways to make it your own:
Add a tassel. A small yarn tassel attached to the end of the keychain adds movement and a boho-chic feel. Cut 10–12 strands of thread about 4 inches long, fold them in half, and attach them through the end loop using a lark’s head knot. Trim to even them out.
Incorporate beads. If you thread small seed beads onto your crochet thread before starting, you can slide one bead into place with each chain stitch for a beaded cord effect. This looks especially stunning with metallic thread and clear or silver beads.
Try a two-color version. Work the cord sections in one color and the petals in a contrasting color for a bold, graphic look. You can either cut and rejoin yarn for each section or carry the second color loosely along the back of your work.
Make it chunkier. For a more casual, everyday look, try the pattern with worsted weight yarn and a 4mm hook. The petals will be larger and more textural, and the finished piece will have a comfortable, cottagecore aesthetic.
Swap the petals for leaves. Instead of the rounded petal shape (sc, hdc, dc 3, hdc, sc), try working sc, hdc, dc, tr, dc, hdc, sc for a slightly elongated leaf shape. This creates a botanical-style design that pairs beautifully with earthy, natural-colored thread.
Selling Your Petal Loop Lanyards and Keychains
If you’re a maker who sells finished crochet items, petal loop lanyards and keychains are an excellent addition to your shop or craft fair table. They’re inexpensive to make in terms of materials, they photograph beautifully, and they appeal to a wide audience. Teachers especially love them for holding ID badges or classroom keys.
When pricing your handmade items, remember to account for the cost of your materials, your time, and any overhead like packaging or marketplace fees. Even at a low price point, a batch of keychains made in an evening can add up to meaningful income.
Consider making them in sets — a matching lanyard and keychain in coordinating colors makes a lovely gift set that’s easy to package in a small organza bag with a ribbon.
Caring for Your Petal Loop Lanyard
Because these are made from cotton thread, they’re generally machine washable on a gentle cycle in a mesh laundry bag, or hand washable in cool water. Avoid wringing or twisting the piece — instead, press it gently between two clean towels to remove excess water, then lay flat to dry. Most cotton threads hold their shape and color well through repeated washing, which makes this a practical everyday accessory as well as a pretty one.
Avoid hanging your lanyard to dry, as the weight of the wet thread can stretch the cord over time. Flat drying keeps everything looking crisp.
Frequently Asked Questions
Can I use regular yarn instead of crochet thread? Absolutely. Any lightweight yarn will work, though the finished look will vary depending on the fiber. Cotton yarn creates a structured petal, while a softer acrylic or blend will give a slightly more relaxed drape. Adjust your hook size to match your yarn weight.
How long does this project take? Most crocheters familiar with basic stitches can complete the keychain in 20–30 minutes and the full lanyard in about 1 to 1.5 hours. It’s an ideal project for evenings in front of a movie or podcast.
Is this pattern suitable for beginners? Yes, with a small caveat. The stitches themselves are simple and beginner-friendly, but working with fine crochet thread can be a little tricky if you’re used to bulkier yarn. If you’re new to thread crochet, I’d recommend practicing your tension on a swatch first. Once you’re comfortable, the pattern comes together very quickly.
Can I make this pattern without a key ring or clasp? Of course. You could simply create a loop at each end of the lanyard and use it as a decorative cord or bookmark. The pattern is flexible enough to be adapted for many different uses.
Final Thoughts
The petal loop lanyard and keychain pattern is one of those projects that delivers a lot of reward for a small investment of time and materials. It’s the kind of thing you’ll find yourself making again and again — experimenting with different thread colors, adding embellishments, and refining your technique with every new piece.
Whether you’re a seasoned thread crocheter or just dipping your toes into finer work for the first time, this pattern offers a satisfying challenge without being overwhelming. The finished result is genuinely wearable and useful, which makes it all the more gratifying to complete.
