Open Crowns

Open crowns are used to create hand shaped fedora and trilby hats but can also be used as they are without any additional hand shaping. They can be made in any height and any oval. If you require a different height to the listing, please specify on the quote form, you can also let us know if you want anything other than the standard oval form. Discounts on sets of blocks are available.

  • A personal service

    Dedicated to providing you with the best hat blocks you can buy - here at Guy Morse-Brown, our focus is firmly on working with you to make your own personal creations.

    To make things with your hands is a fundamental part of human nature and whether it is the weaver, the felt maker, the block maker, or you the milliner, we are all part of a process that culminates in something that is more than just an object to admire - it is a statement, an expression that enriches the life of the wearer and creator alike.

    We feel that the parts of the process shouldn't be completely separated so we want to work with you to enable us both to share in it all. For that reason you won't find online ordering here on our website but you will find a huge range that shows that almost anything is possible. It's too simple to just add products to a cart; we want to keep alive the personal communication between block maker and milliner that used to be so essential. Get in touch with us and share your ideas, let us know what you want to make and we're ready to serve.

    They are almost too beautiful to use.
