Naka-Kon 2026 Advanced Seam Finishes for Cosplay Workshop

Skill Level: Advanced

In this advanced, machine-based workshop, you’ll learn how to create a range of polished, durable seam finishes using a standard home sewing machine without needing an overlock machine or serger. We’ll break down when and why to use different finishes depending on fabric type, costume structure, and wear demands, then walk through each technique step-by-step. Students will practice multiple seam finishes and leave with the confidence to choose the right one for any cosplay project.

Special prizing for sewing workshop attendees: Anyone who purchases a ticket and attends a sewing workshop will be entered into a drawing to win one of two Bernette sewing machines! Winners will be announced at closing ceremonies, and must be in attendance to win. 

You can exit the Overland Park Convention Center (OPCC) by the double doors at the front, near registration. From there it is a 5-10 minute walk, with a sidewalk that goes along the building. You may also use the complimentary shuttle service that picks up riders in the circle drive right in front of the Sheraton Hotel.

A Naka-Kon 2026 convention membership badge is required to attend all ticketed events.
