Materials and tools are provided
Restricted to Course Eén participants

Prolong the learning experience from Course Eén and learn to make four different woodworking joints!

What will you learn?


The blind mortise and tenon

The mortise and tenon joint is one of the most common joints in woodworking. The first joint you will learn to make is the blind variant of the mortise and tenon joint.


The through mortise and tenon

The through mortise and tenon is another variety of the same joint and requires a little bit more work and precision than the blind one.


The box joint

A very common wood joint used for case constructions is the so-called box joint, sometimes also known as the finger joint. This is the joint we will learn to make in the third lesson.


The dovetail joint

We will end the course with the most characteristic of the all the joints: the dovetail joint.

Follow these steps to register a course.

  1. View the course schedule and pick a date that suits you.
  2. Click the “Register” button behind the preferred date. This will add the course to your online cart and automatically show you the contents of your cart. If you see no register button, it is because that class is already full!
  3. Check the contents of your cart and click the “Proceed to Checkout” button.
  4. Provide your details, choose a payment method, and follow the instructions on the checkout page.

The registration will only be completed once you have concluded the checkout procedure and fulfilled the payment of the course fee.

Payment of the course feeexpand_more

You are required to pay the course fee immediately when booking a course. It is not possible to delay the payment to a later date, nor to reserve a spot without payment.

Below you can see what payments methods are accepted. The payment method can be chosen during the booking procedure. Payments are processed in a fully secure environment by our partner Mollie, an established payment service provider.

Cancellation and refundexpand_more

  • If you cancel your booking at the latest 10 days before the start of the course, the total course fee will be refunded to you, minus a €6.95 service charge.
  • If you cancel your booking between 9 and 5 days before the start of the course, 50% of the total course fee will be refunded to you, unless a replacement can be found. In that case the total course fee will be refunded to you, minus a €6.95 service charge.
  • Cancellations and refunds are not possible within 4 days (96 hours) before the start of the course, unless replacement can be found. If replacement is found, the total course fee will be refunded to you, minus a €6.95 service charge.
  • In case you have used a course voucher, there will be no refund. Vouchers are not redeemable.

To cancel your booking, send an email to with your request and booking order number.

Refunds will be carried out within 14 calendar days from the day we receive your cancellation note. We will use the same payment method as you did, unless otherwise agreed.

Transfer to another classexpand_more

It is possible to be transferred to another class up till 10 days before the start of the course that you originally booked. How this transferring works depends on the following situations:

  1. Spots announced in course availability alert
    Spots that were announced in the course availability alert (the newsletter) are not available for transfers until 12 hours after the publication time mentioned in the course availability alert. Transfer requests send before or within these 12 hours will not be processed!

    If you do not want to wait out of fear that the spot(s) may sell out within those 12 hours, you are free to directly book the spot yourself at the given publication time through the normal online booking procedure (i.e. as you were a new customer) and subsequently cancel your previous booking. Please note that, in that case, the cancellation and refund conditions explained on this page will apply.

    This policy is to ensure that all subscribers to the course availability alert have an equal chance to obtain the announced spot(s).

  2. Open spots in course schedule
    For spots that just appear available in the course schedule and for which the conditions mentioned above at 1. do not apply, just send an email to with your request for a transfer and the order number of your original booking.

  3. No (suitable) classes available?
    If there are no other classes available in the course schedule or if the available classes don’t suit you, then your only option left is cancelling your registration altogether and book anew when new classes are added to the schedule. It is not possible to reserve a spot in a future class that is not yet scheduled. For more about cancellation and refunds, please read this page.

Transferring within 9 days of the start of the course is not possible and any requests in this respect will be dealt with similar to cancellation requests within the same term.

Offer this course as a gift to someoneexpand_more

It is also possible to offer this course as a gift to someone else. You can do so in two ways:

  1. Choose a class yourself in the schedule above and book it for the recipient. If you want to keep it a surprise for the time being, fill in your own contact details during the registration.
  2. Buy a gift voucher and give the voucher to the recipient. The recipient can choose a class themselves depending on their availability and use the voucher for payment. Click here to buy a voucher.
    Note that vouchers are not available if there are not enough classes available in the schedule. With limited availability, there is nothing or too little to choose and that defeats the whole purpose of the voucher. In this case, you can revert to the first option.

The more woodworking joints you know, the more things you will be able to create. That is why Course Twee aims to expand your knowledge about traditional joints and teaches you different woodworking joints.

As a participant, you will

  1. Acquire knowledge about traditional joinery in general
  2. Learn to make four different traditional woodworking joints
  3. Learn new skills with hand tools
  4. Develop your skills from Course Eén to a higher level

Attention: Course Twee is part of an integral learning trajectory offered by Atelier Espenaer that starts with Course Eén. Course Twee can only be joined by participants of Course Eén!

emoji_peopleFor who is this course?


Course Two is only accessible to participants of Course Eén. This is because Course Two is part of a integral learning trajectory that starts with Course Eén. The aims and contents of the two courses are tuned to one another.

groupsClass size


The courses are explicitly focused on individual guidance and personal contact with (and among) course participants. For this reason, the number of participants per course is limited to a maximum of 6.

The small size of the class makes it easy to switch between plenary instructions and individual guidance. If you don’t fully understand something or need help with a particular skill, you will easily and quickly be assisted by the instructor, because there are just 6 participants in the group, including you!

Similarly, because the instructor is overseeing just the 6 of you in the workshop, he can quickly step in if he sees that you are doing something wrong, even when you are not aware of it yourself.



The courses are offered in Espenaer’s own atelier, located in Het Ambachtslab in Amsterdam-West. The atelier is easy to reach by bike, car, and public transportation. There is ample parking space in front of the building (Paid parking). Participants will receive more detailed directions upon registration.

schoolAbout the instructor


The courses are instructed by artisanal furniture maker and founder of Atelier Espenaer, Umut Lucas Espenaer. Umut has over 15 years of experience in woodworking and specializes in artisanal skills, techniques, and hand tools. He originally started woodworking as a hobby before turning it into his trade and is self-taught. He has been offering woodworking courses since 2017 and has had the pleasure of instructing to several hundreds of participants up till now.

For a furniture maker, Umut has a somewhat unusual professional background. He was originally trained as a political scientist and worked as policy officer at the Dutch Ministry of Foreign Affairs and as lecturer at the University of Amsterdam for most of his professional life. He decided to switch careers and pursue his passion, left his career in academia, and founded Atelier Espenaer. He is very passionate about artisanal woodworking and enjoys helping others explore their own creativity.
