I have been making stabilizers and interlinings for 33-34 years now.
I teach stabilizing in many venues NNEP, ISS, VDTA , Hands on Sweing Schools and elsewhere.
You will learn the simplified tecniques behind stabilizing.
We will of course go over when to use a tearaway vs a cutaway.
We will go over what not to use and when and also What stabilizer to use for each specific embroidery application.
