Welcome

This blazer also has some soft tailoring to add to your sewing skills. Knit interfacing provides structure to the chest and upper back, and woven interfacing reinforces the collar.

Keaton is a rewarding make that you’re sure to love.

In this class, you’ll learn:


  • Tips for selecting fabric and notions

  • How to attach the lining

  • How to sew the lapels and collar
