Hat Customisation & Crafting

Reshape, retrim, and personalise your hats. From simple band swaps to bespoke millinery techniques, custom hatmaking, and the art of blocking.

Hat Customisation & Crafting

A hat off the shelf is a starting point. Making it yours — through reshaping, trimming, and personalisation — is where the real character begins.


Quick Customisations (No Special Tools)

Swap the Band

The fastest way to transform a hat. Most hat bands are held in place by friction or a small bow/knot — they slide off and on.

Band TypeEffectWhere to Find
Grosgrain ribbonClassic, cleanHaberdashery shops, online
Leather bandRugged, westernLeather craft suppliers
Woven/patterned fabricPersonality, colour popFabric shops, vintage stores
Braided cordCasual, bohemianCraft shops
Feather accentTradition (Alpine, hunting)Millinery suppliers
Vintage brooch on existing bandStatementAntique shops, charity shops

How: Measure the circumference of the hat at the crown-brim junction. Add 5 cm for overlap. Secure with a few stitches or a small safety pin at the back.

Add a Pin or Brooch

  • A lapel pin on the hat band adds instant personality
  • Vintage brooches, enamel pins, and small medallions all work
  • Place on the left side (tradition) or wherever looks best to you

Adjust the Fit

  • Too loose: Add adhesive foam hat sizing tape inside the sweatband. Available from hat shops and online (sold in strips)
  • Too tight: Stretch the hat gently over a hat stretcher or slightly oversized round object. For felt hats, steam lightly first to make the felt pliable. Increase gradually — felt has limits

Reshaping Felt Hats

Felt hats are the most customisable hats because felt is thermoplastic — steam softens it, and it holds whatever shape it dries in.

What You Need

  • A kettle or garment steamer (steamer is easier and safer)
  • Clean hands
  • A form to dry on (your head, a hat stand, or a bowl for the crown)

How to Reshape

  1. Steam the area you want to reshape. Hold the hat 15–20 cm above the steam source. Rotate slowly. The felt should feel warm and pliable after 15–30 seconds
  2. Shape with your hands. Curl the brim up or down. Adjust the crease depth. Reshape the pinch. Work gently — felt responds to firm but not aggressive shaping
  3. Hold the shape until the felt cools and dries. This usually takes 30–60 seconds. For brim curves, you can use a few books or a heavy mug to hold the brim in position while drying
  4. Repeat if needed. Multiple light steaming sessions are safer than one heavy one

Bespoke Hatmaking — An Overview

Bespoke (custom) hatmaking is alive and well, though rare. A bespoke hat is made to your specific head measurements, face shape, and style preferences.

The Process

  1. Consultation — discuss style, colour, material, purpose
  2. Measurement — head circumference, head shape (oval, round, long oval), and head depth
  3. Blocking — a hat form (block) matching your measurements is selected. The felt or straw is steamed and stretched over the block
  4. Shaping — brim width, crown height, crease style, and brim curve are set
  5. Finishing — sweatband fitted, edge binding applied, band and trim added
  6. Fitting — final adjustment on your head

Where to Get One

  • Lock & Co. (London) — bespoke from the oldest hat shop in the world
  • Optimo Hats (Chicago) — handmade American classics
  • Worth & Worth (New York) — modern American bespoke
  • Local milliners — many cities have small-scale milliners who do custom work. Search for "bespoke milliner" in your area

Cost

  • Bespoke felt hats typically start at £250–400 and can exceed £1,000 for premium materials
  • The hat will fit perfectly and last decades with proper care
  • Many bespoke hatmakers include lifetime reshaping and maintenance

DIY Hat Trimming

If you want to add more substantial decoration:

Feathers

  • Traditional on fedoras (small accent feather), Alpine hats (Gamsbart — a brush of chamois hair), and country hats
  • Secure with a small stitch through the band, or tuck behind the band
  • Source: millinery suppliers, craft shops, or ethically sourced feather dealers

Flowers and Botanicals

  • Silk or dried flowers on women's hats — a millinery tradition
  • Can be wired and stitched, or pinned for removability
  • Sinamay (a stiff fabric made from abaca fibre) is the standard base for decorative pieces

Embroidery

  • Baseball caps and bucket hats take embroidery well
  • Hand-embroidered initials or small motifs add personal character
  • Machine embroidery services can add logos or text ($5–20 per hat at many embroidery shops)

Painting

  • Fabric paint and markers work on cotton and canvas hats
  • Posca paint pens (acrylic-based) are popular for custom baseball cap art
  • Seal with fabric sealant spray for durability

Hat Blocking — The Core of Hatmaking

Blocking is the fundamental technique of hat construction — stretching a flat or cone-shaped piece of felt or straw over a wooden form (block) to create a 3D hat shape.

How It Works

  1. The hat body (a cone or capeline of prepared felt or straw) is soaked in water (straw) or steamed (felt) until pliable
  2. It's placed over a wooden block shaped to the desired crown form
  3. A string or drawstring is tied at the base to hold the material tight against the block
  4. The hat is left to dry completely on the block (hours to overnight)
  5. Once dry, it holds the block's shape. The brim is trimmed to width and the edges are finished

For Hobbyists

  • Beginner hat-blocking kits are available from millinery suppliers (Parkin Fabrics, Judith M, Hat Academy)
  • A basic kit includes a crown block, brim block, drawstring, and instructions
  • Start with wool felt or sinamay — they're forgiving and affordable
  • A steamable hat body costs £15–30; wooden blocks cost £40–200+ (but last forever)
