Hollow form construction is a great method for making very three dimensional and light shapes, and an excellent way to understand how sheet metal moves! Thinking in full 3D opens up many doors for your designs and also for your technical skills- especially working on fabrication issues and adapting to acheive the result you want in your pieces!

In this class, we start off by fabricating the basic shapes: cyliner, cube, sphere, cone, and pyramid. Then we move on to how to combine those shapes together into complex shapes. Students will learn how to use stakes, dapping tools, and punches to form and adapt their metal for seamless connection and fluid shapes. We will also talk about designing forms, how to map out your shapes and translate them into a 2D pattern and templates. 

Join us for this exciting and informative dive into working with sheet metal in new ways! 

This course is available as an in-person workshop or live online class. Please check this page for times and formats available.

If a class is online, or is a combination online and in-person session, all students receive a link to a recording of the class demonstrations. In-person only workshops are not recorded.

If a kit is included with the class, online students will have them mailed to them. Kits for in-person students are delivered at the beginning of the first class. More information about the kit is included with the supplies list which is emailed after registration.

International students may be charged an additional amount for shipping, because of the increased cost to ship abroad. Also, shipments to other countries may incur a tariff payable by the student. International students are welcome to contact us re: these costs and options for their materials. Please be sure that the address with your payment is the correct one for shipping.

If this class is offered online, it uses the Zoom app/website. Through Zoom, you’ll be able to see demos and follow instructions, ask questions and interact with your instructor. Zoom is easy to use and free for students to use for class, and works on most devices, like phones (iPhone, Android, etc), tablets (iPads, etc), and computers (Mac or PC).

Your instructor is also available during free Zoom office hours for questions and help.

Online students work at home or in their studio. All of our recommended tools and the kit materials are chosen to be home studio friendly. Links to preferred vendors are provided in the supplies list sent after registration.

For the health and safety our staff and students, students are required to show proof of vaccination and to wear masks when attending classes at our school. If you can’t meet these requirements, we invite you to take the online version of this class instead, if available. Please visit our COVID-19 Updates page for more information.

And now the fine print. Payment in full for class fees is due at the time of registration to reserve your place. We accept Visa, MasterCard, American Express, Discover, and PayPal. Checks and cash are accepted only if you register at school. If you mail a check, your registration is not processed until it clears and the class may fill during the wait. 

If the workshop is canceled by our school for any reason, all class fees will be refunded, or you can transfer to another class, or you can keep a credit on account with us for future classes or purchases, 

Students can cancel, receive a credit or refund, or transfer to another class up to 21 days before a workshop, whether it is online or in person. No cancellations are accepted after the 21-day deadline, however, we will do what we can to try and sell your place to a qualified student. If we can sell your place, you can receive a refund less a $50 cancellation fee, keep a credit on account with us, or apply your fees towards a transfer to another class. 

If you can’t make it to class, you may send a participant who has the necessary prerequisites in your place. Please call or email us immediately with any changes in the student participant information. If a class includes an online section, your class will be recorded and you can watch later to make up a class you miss. 

Students must be at least 15 years old to attend a class, and students under 18 must have a legal guardian sign our liability waiver form. We have had younger students attend classes, on a case by case basis. If you’re interested in enrolling your child, please call or email us.
