This document will help you understand the different types of interfacings available and how to use them. I've added my video link to my live-stream Interfacing Discussion from 2023 in case it helps.

As always, you have to do what works for YOU. I'm not suggesting I know it all, or that you have to do it my way. NOT AT ALL. Find what works for you and keep going, keep pushing your skills, and keep learning. 🤭🤗
What's Inside the Interfacing Guide
The guide covers the most common interfacings used in bag making, including fusible fleece, foam stabilizer (like Soft and Stable), woven fusible, non-woven fusible, and sew-in options. I break down when to use each one, how to apply them, and what to avoid.
Fusible vs. Sew-In: Which Should You Use?
Fusible interfacing bonds to your fabric with heat — fast and easy, great for structured bags and exterior panels. Sew-in interfacing is stitched in place and is better for delicate fabrics that can't handle an iron, or when you want a softer drape. Both have their place in bag making and I cover both in the guide.
Tips Before You Start
A few things I always tell beginners: if you plan on washing your bag, pre-shrink your interfacing if it's sew-in, use a pressing cloth to protect your iron, and test on a scrap first. The wrong interfacing can make a beautiful fabric stiff and sad — or worse, bubble and peel after washing. The guide will help you avoid those mistakes.
Watch the Live Discussion
I did a full live-stream on interfacing in 2023 where I answered questions in real time. It's linked below and pairs perfectly with the PDF — watch it while you have the guide open for the best experience.
Peace, Love, Sewing,
