What Is a Crochet Bun Beanie?
A bun beanie (sometimes called a ponytail beanie) is a hat crocheted with an opening left at the top, so that hair worn up in a bun or ponytail can be pulled through while the rest of the head stays covered. It’s a practical style for anyone who wears their hair up in cold weather and doesn’t want to choose between a warm hat and keeping their hairstyle intact.
Materials You’ll Typically Need
Based on the detailed pattern reviewed for this guide, a bun beanie made in bulky (#5) weight yarn typically calls for:
- Bulky weight yarn, roughly 120-160 yards (about 3.5-4 oz) depending on size
- A hook sized for bulky yarn — a 6.5mm (US K) hook is used in the version referenced here
- A yarn needle and scissors
- A hair elastic (optional — some versions start by working directly around a hair elastic instead of a crocheted ring)
Some designers in this style also offer a version worked in medium (#4) weight yarn, or suggest holding two strands of medium weight yarn together as a substitute for bulky yarn — worth keeping in mind if bulky yarn isn’t what you have on hand, though gauge and finished size will shift accordingly.
Sizing: What to Expect
The one detailed source behind this overview includes four sizes — child (3-10 years), teen/adult small, adult medium, and adult large — with a published size chart along these lines:
| Size | Head Circumference | Hat Circumference |
|---|---|---|
| Child (3-10 yrs) | 19-20 in | 17 in |
| Teen/Adult Small | 21 in | 18 in |
| Adult Medium | 22 in | 19 in |
| Adult Large | 23 in | 20.5 in |
These numbers come from a single designer’s pattern rather than an industry standard, so treat them as a reasonable starting reference rather than a fixed rule — if you’re working from a different pattern, check its own size chart and gauge before choosing a size.
How Bun Beanies Are Usually Constructed
The general construction approach seen in bun beanie patterns is:
- Start either by chaining a small ring around a hair elastic, or by chaining and joining a ring on its own (without an elastic) to form the top opening.
- Work rows back and forth in half double crochet, often worked in the back loop only to create a ribbed texture, with a single crochet worked around the center opening periodically to reinforce it.
- Continue rows until the piece reaches the needed length for the chosen size.
- Fold the rectangle of fabric in half and seam the two open edges together (often worked through the front loops of the last row and the starting chain) to form the sides of the hat, leaving the folded edge as the brim.
Because the hat is built as a flat, folded rectangle rather than worked in the round from the crown down, the “rows going diagonal instead of straight” issue some crocheters report is usually a tension or gauge mismatch rather than a mistake in the stitch pattern itself — if that happens, it’s worth checking your HDC-BLO tension before continuing.
Tips for Customizing the Fit
A few adjustments mentioned in the pattern researched for this guide:
- To change the brim height, adjust how long the starting chain is before folding.
- To change the overall hat circumference, add or remove rows (while keeping an even number so the seam lines up correctly).
- The pattern is generally written with a small amount of negative ease (finished hat circumference smaller than head circumference) to account for stretch.
Where to Find a Free Written Pattern
Free, fully written bun beanie patterns are less common in general search results than you might expect — many top results for this topic are video tutorials or Pinterest pins rather than text patterns, and some listings (including a Ravelry pattern found during research) were not accessible for review. The detailed written pattern referenced throughout this guide comes from an independent crochet blog that also publishes a paid, ad-free PDF version of the same pattern alongside the free blog post.
If you want a hat with a similar easy construction but without the bun opening, the elf beanie pattern uses a comparable ribbed-brim approach before shaping up into a pointed crown.
FAQ
What yarn weight is typically used for a bun beanie? Bulky (#5) weight yarn is common, though some designers offer medium (#4) weight versions or suggest holding two strands of medium weight yarn together as a substitute.
Do I need a hair elastic to make a bun beanie? No — most patterns offer two starting options: working directly around a hair elastic, or chaining and joining a ring on its own to form the top opening.
Why are my rows coming out diagonal instead of straight? This is generally a tension issue rather than a mistake in the pattern itself, especially in stitches worked in the back loop only — checking your gauge and keeping consistent tension usually resolves it.
Can I adjust the size of a bun beanie pattern? Yes, most patterns note that you can add or remove rows to change the circumference, and adjust the starting chain length to change the brim height, though you may need to adjust the final seam placement to keep it even.
