Not every sizing problem needs a new block — sometimes an existing hat just needs to be stretched a little, evened out, or adjusted across a range of sizes. Formillionaire’s stretching and sizing tools cover exactly that: an oval hat stretcher for gently expanding a finished hat, and the Formillion expansion kit for working across a wide 54-64cm size range with one tool.

Adjusting Instead of Reblocking

A stretcher works from the inside of an already-blocked hat, expanding it gradually and evenly rather than forcing a single spot — useful for a hat that’s a touch too tight, or for standardizing a batch of hats that came out slightly inconsistent.

What’s in the Range

  • Oval Hat Stretcher
  • Formillion Expansion Kit (54-64cm)
  • Formillion Hat Stretcher & Sizing Tool

Get the Size Right From the Start

Prefer to block to the correct size the first time? The brim plate generator reads the real hat size straight off your traced outline’s circumference, so you know what you’re printing before you ever pick up a stretcher.
