Use this interfacing and stabilizer selector to get a general starting point for your bag making project.
Interfacing and stabilizer are not the same thing. Interfacing helps support the fabric and reduce stretching. Stabilizer adds structure, body, and shape to the finished bag.
For most bag making projects, cotton fabrics should be interfaced first with a woven interfacing such as Sew Woven™ or a similar style woven interfacing. Stabilizer may then be added in addition to interfacing when you want more structure.
Helpful Tip: Always check the pattern instructions first. If the pattern designer recommends a specific interfacing or stabilizer, use that as your main guide.
Some faux leathers, vinyls, cork, or specialty materials may also need interfacing if they have one-way stretch or feel unstable. Always test on scraps first.
Stabilizer choice is more personal. Some bag makers prefer a soft, flexible bag, while others like a firmer bag that stands on its own.
Your fabric, desired structure, sewing machine, needle, thread, number of layers, and bag style can all affect which combination works best.
