Free Knitting Pattern: Lydia Lace Hat — A Beautiful One-Skein Project
There is something deeply satisfying about casting on a hat. It is one of those projects that feels manageable from the very beginning — you can see the finish line before you even start — and yet a beautifully finished hat carries real weight, the kind of handmade object that someone will reach for year after year. The Lydia Lace Hat is exactly that kind of project. It is elegant without being fussy, challenging without being frustrating, and it uses just one skein of yarn, which means you can justify buying that gorgeous single skein you have been eyeing at your local yarn shop without a single moment of guilt.
Whether you are a knitter who has been working with needles for decades or someone who has just conquered the basics and is ready to try something with a little more visual interest, this pattern is for you. The lace pattern at the brim gives the hat its name and its character, while the rest of the construction is straightforward and satisfying to work. By the time you finish your first Lydia Lace Hat, you will probably be reaching for another skein to make a second one.
Let us get into everything you need to know.
About the Lydia Lace Hat
The Lydia Lace Hat is a top-down or brim-up knitted hat (this version works from the brim up) featuring a delicate lace border that transitions into a simple stockinette body before shaping at the crown. The lace pattern is a classic, timeless design — think gentle eyelets arranged in a repeating sequence that catches the light beautifully and adds a feminine, refined touch to what would otherwise be a plain beanie.
The hat is sized for an average adult head (approximately 20–22 inches in circumference), but notes are included to help you adjust the sizing if needed. It is worked in the round on circular needles, so there are no seams to sew up at the end, which means your finishing work is minimal and the inside of the hat looks just as tidy as the outside.
One skein is all you need. This makes the Lydia Lace Hat a perfect project for gifting, stash-busting, or experimenting with a yarn you have never worked with before.
Materials You Will Need
Before you cast on, gather your supplies. Having everything ready before you sit down to knit makes the process feel much more relaxed.
Yarn: 1 skein of worsted weight yarn, approximately 200 yards. Look for something with a smooth twist and good stitch definition, as this will help the lace pattern show up clearly. A yarn with some wool content is ideal because wool has natural elasticity and the lace will block beautifully. Suggested options include any good-quality merino wool or a merino blend. If you are making the hat as a gift for someone with a wool sensitivity, a smooth acrylic or acrylic-blend in worsted weight will work well too, though the lace may be slightly less defined.
Needles: US size 7 (4.5 mm) 16-inch circular needles for the body of the hat, plus a set of US size 7 double-pointed needles (or a second circular or a longer circular for magic loop) for the crown shaping. If you prefer to use a longer circular needle throughout and work the crown decreases with the magic loop method, that works perfectly.
Notions: Stitch marker (at least one, to mark the beginning of the round), yarn needle for weaving in ends, scissors, and a tape measure. If you plan to block the finished hat (highly recommended to open up the lace), you will also want blocking mats and rust-proof pins, plus a clean towel.
Gauge: 20 stitches and 28 rows = 4 inches in stockinette stitch on US size 7 needles. Please, please swatch. Gauge is especially important with a hat because a small difference in your stitch count per inch adds up around the full circumference of the hat. If your gauge is off, your hat may end up too tight or too large, and with a fitted project like this, that matters. Swatch, measure, and adjust your needle size as needed before casting on the hat itself.
Sizing
This pattern is written for one size with notes for adjustment.
Finished circumference: Approximately 19 inches (designed to fit a 20–22 inch head with natural stretch)
Finished length: Approximately 9 inches from brim to crown before blocking
To make the hat smaller (for a child or a smaller adult head), work the lace section as written and then decrease your stitch count by 8 stitches evenly across the first plain round of the body. To make the hat larger, add 8 stitches evenly across that same round.

The Lace Pattern
The lace section of the Lydia Lace Hat is built on an 8-stitch repeat worked over 10 rounds. Before you begin the hat, it helps to read through the lace chart description once so you understand how the pattern moves.
The basic logic of the lace is this: yarn overs create the holes (eyelets), and paired decreases on either side of those eyelets compensate so your stitch count stays the same. The result is a flowing, leaf-like or vine-like texture that ripples gently around the brim of the hat.
Lace Pattern (worked over a multiple of 8 stitches, in the round):
Round 1: K3, YO, SSK, K3; rep from to end
Round 2 and all even rounds: Knit all stitches
Round 3: K1, K2tog, YO, K1, YO, SSK, K2; rep from to end
Round 5: K2tog, YO, K3, YO, SSK, K1; rep from to end
Round 7: K2, YO, SSK, K1, K2tog, YO, K1; rep from to end
Round 9: K3, YO, K3tog, YO, K2; rep from to end
Round 10: Knit all stitches
Work rounds 1–10 twice for the full lace section (20 rounds total). This gives the brim enough depth that the lace pattern is fully visible even when the hat brim is folded or worn unfolded.
If you are a visual learner and prefer to work from a chart, this pattern is easy to chart out on graph paper using standard lace notation. The 10-round, 8-stitch repeat is a clean rectangle that tiles neatly.
Pattern Instructions
Cast On
Using your US size 7 circular needles and the long-tail cast on method (or your preferred stretchy cast on), CO 96 stitches. Join to work in the round, being careful not to twist your stitches. Place your stitch marker to mark the beginning of the round.
If you find that a long-tail cast on is not quite stretchy enough for you — especially if you have a slightly larger head or like a looser hat edge — try a German twisted cast on or a simple twisted long-tail cast on instead. Both give you more stretch at the brim.
Ribbing
Work K2, P2 ribbing for 8 rounds (approximately 1 inch). This ribbing anchors the lace section and gives the brim a bit of structure so it does not flare outward too much.
Lace Section
Work the 10-round lace pattern twice (rounds 1–10, then rounds 1–10 again) for a total of 20 rounds of lace.
Take your time in the lace section. If you are newer to lace knitting, work in a well-lit space and count your stitches at the end of every round for the first few repeats. You should always end each round with exactly 96 stitches. If you find yourself with more or fewer, it is easy to find the error and fix it before you move on. Lifelines are your friend in lace knitting — thread a smooth piece of waste yarn through your live stitches at the end of a correctly completed pattern repeat so you have a safe point to rip back to if needed.
Body
After completing the lace section, work in plain stockinette (knit every round) for 20 rounds, or until the hat measures approximately 6.5 to 7 inches from the cast-on edge. This is the point where you want to try the hat on (or check it against a head measurement) to confirm you have enough length before the crown shaping begins. The plain stockinette section lets the lace breathe and be admired, and it also makes the crown shaping feel like a natural conclusion rather than an abrupt ending.
Crown Shaping
Switch to double-pointed needles (or continue with magic loop) when the stitches become too few to comfortably span your circular needle.
Setup round: Divide your 96 stitches into 8 sections of 12 stitches each by placing markers after every 12th stitch.
Decrease rounds:
Round 1 (decrease round): K to 2 stitches before marker, K2tog, SM; rep from to end of round — 8 stitches decreased, 88 stitches remain
Round 2: Knit all stitches
Repeat rounds 1 and 2 until you have 16 stitches remaining (8 decrease rounds total, 8 plain rounds between them).
Then work the decrease round every round (no plain round between) until 8 stitches remain.
Finishing the crown: Cut yarn, leaving a 6-inch tail. Thread the tail onto your yarn needle and draw it through the remaining 8 live stitches, removing them from the needle as you go. Pull firmly to close the crown opening, pass the needle to the inside of the hat, and weave in the end securely.
Finishing
Weave in any remaining ends on the inside of the hat. The cast-on tail and the crown finishing tail are the main ones.
Blocking
Blocking is what takes a lace project from nice to wonderful. Even if you are knitting with acrylic, a light steam block or wet block will even out your stitches and open up the lace beautifully.
For a wool or natural fiber hat, soak the finished hat in cool water for about 20 minutes, gently press out the excess water (do not wring), roll it in a clean towel and press to remove more moisture, and then place it over a balloon or hat form inflated to approximately the right size. Pin out the lace points gently at the brim edge if you want the lace to open up more dramatically. Let it dry completely before wearing or gifting.
For an acrylic hat, use the steam setting on your iron held just above (not touching) the fabric to relax the stitches, or use a damp cloth between the iron and the hat.
Tips for Success
The lace section is the heart of this pattern, and a few small habits will help you sail through it with confidence.
Work in good light. Lace knitting requires you to see what you are doing, and dim lighting makes it much harder to track your yarn overs and decreases.
Use stitch markers within the lace repeat if you need to. You can place a removable marker after every 8 stitches (one full repeat) until you have memorized the pattern. Once you can feel the rhythm of it, you will probably find you do not need them anymore.
Read each round before you knit it. It takes thirty seconds and saves you from mistakes that take ten minutes to fix.
Do not tink (unknit) across yarn overs if you can avoid it. Yarn overs are easy to lose when you are working backwards stitch by stitch. If you need to undo work in the lace section, it is often faster and safer to rip back to your lifeline.
Keep your yarn overs loose and even. Tight yarn overs close up the eyelets and make the lace look pinched. A relaxed tension is your friend in lace.
Yarn Recommendations
Because this pattern uses only one skein, this is a wonderful excuse to treat yourself to a special yarn. Here are some qualities to look for and a few directions to point you.
A smooth, plied yarn will show lace definition better than a single-ply or textured yarn. Superwash merino in worsted weight is a lovely choice — it is soft against the skin, easy to work with, and blocks beautifully. Many indie dyers produce stunning hand-dyed skeins in worsted weight that would make this hat look absolutely spectacular.
If you want something more practical and machine washable, a merino-nylon blend or a high-quality acrylic like Lion Brand Pound of Love or Paintbox Simply DK held double (though note this changes your gauge, so swatch carefully) can work well.
For a warm winter hat with more heft, a wool-alpaca blend adds beautiful drape and warmth while still giving you enough stitch definition to see the lace.
Gifting the Lydia Lace Hat
A handmade hat is one of the most appreciated knitted gifts you can give. It is practical, wearable, and immediately useful. The Lydia Lace Hat walks a lovely line between functional and beautiful — it is clearly handmade in the best possible way, with visible craft and care in every stitch of the lace border, but it is also just a hat that someone can grab and wear on a cold morning without feeling precious about it.
Consider pairing the finished hat with a matching cowl or fingerless mitts in the same yarn for a coordinated gift set. The lace pattern from the brim could be adapted to work as a cowl with very little modification.
If you are making the hat as a gift, it is worth asking about the recipient’s head size before you cast on, since even an inch or two of difference can affect the fit. A hat that fits well is a hat that gets worn.
Final Thoughts
The Lydia Lace Hat is the kind of pattern that earns a permanent spot in your project queue. Once you have knitted it once, you know the rhythm of it — the ribbing, the lace, the long satisfying stretch of stockinette, the satisfying spiral of the crown decreases — and the second one goes faster and feels even more enjoyable. It is the kind of pattern you return to when you want to knit something beautiful without consulting the instructions every thirty seconds, and it is the kind of finished object that makes everyone around you say, “Did you make that?”
Yes. You did.
Cast on and enjoy every stitch.
