Hat Block (#81 LONG oval) ABS UPGRADE

#81 Long Oval Hat Block — ABS Plastic

Our hat blocks are made to order, so please allow 5–7 business days for processing before shipping. Need yours sooner? Contact us to discuss availability, or browse our Misfits section for in-stock blocks!

Our #81 Long Oval Hat Block is designed for milliners and hat makers who need a more elongated front-to-back crown profile with the added durability and heat resistance of ABS plastic.

The #81 features a classic tapered crown combined with a long oval footprint, making it ideal for projects that require more front-to-back length than a regular oval block.

Each block is 3D printed for consistency and made to the selected size.

⚠️ IMPORTANT SIZING INFORMATION

Our hat blocks are made TRUE TO SIZE.

The listed size is the actual circumference of the hat block.

YOU MUST ORDER ONE SIZE LARGER THAN YOUR FINISHED HAT SIZE TO ALLOW ROOM FOR THE SWEATBAND.

For example:

If you are making a finished 58 cm hat, order a 59 cm hat block.

The additional size provides the necessary allowance for the sweatband and helps prevent the finished hat from fitting too tightly.

#81 Long Oval Profile

The #81 features a traditional tapered crown with a long oval profile.

The long oval shape provides additional front-to-back length compared with a regular oval block, making it a better fit for longer, narrower head shapes and hat styles that require a more elongated footprint.

If you need a more traditional, balanced oval shape, please see our #81 Regular Oval Hat Block.

ABS Plastic Construction

This version of the #81 is printed in ABS plastic.

ABS is a strong, durable material with improved heat resistance, making it a good choice for hat makers who prefer a more temperature-resistant block material during their blocking process.

Because these blocks are 3D printed, minor layer lines or surface variations may be visible. These are a normal part of the manufacturing process and do not affect the function of the block.

Choosing Your Size

Measure the intended finished head size, then order the next size larger.

Finished Hat Size → Recommended Block Size

56 cm finished hat → 57 cm block
57 cm finished hat → 58 cm block
58 cm finished hat → 59 cm block
59 cm finished hat → 60 cm block
60 cm finished hat → 61 cm block

Half sizes may also be available depending on the selected size options.

True-to-Size Construction

Because our hat blocks are made true to the listed size, we do not automatically add extra circumference for sweatbands, liners, or other finishing materials.

This allows the hat maker to select the amount of sizing allowance appropriate for their project.

Returns & Incorrect Size Orders

Please carefully check both the size and profile before placing your order.

Because our hat blocks are made true to size, it is the buyer's responsibility to select the correct size and to order one size larger to allow for the sweatband.

Returns resulting from an incorrect size or style being ordered by the customer are subject to a $10 return fee.

If you are unsure whether the Regular Oval or Long Oval profile is right for your project, please contact us before ordering.
