My Finished Bag Is Too Soft - How Can I Make It More Structured?

If your finished bag feels softer or doesn't hold its shape as well as the bag shown in the pattern, the most likely reason is a difference in the interfacing or stabiliser used.

Unfortunately, once a bag is completely assembled, there generally isn't a practical way to add more structure without taking it apart. The good news is that it's usually quite easy to adjust the next one! 😊

First, check the stabiliser you used

If you substituted the foam or firm stabiliser listed in the pattern, that's the first thing I would look at.

Products that appear similar aren't always equivalent. Foam, fleece, batting and firm stabilisers all behave differently in a finished bag, and even products within the same category can vary in firmness.

For the result closest to my pattern samples, I recommend using the type of stabiliser specified in the pattern, or a comparable substitute.

Did you interface all cotton fabrics?

I normally recommend adding a woven fusible interfacing to all cotton fabrics in my bags, including both cotton exteriors and linings.

This supports the fabric itself and can make quite a noticeable difference to the body and overall finish of the bag.

If your exterior fabric wasn't interfaced, adding woven fusible interfacing next time may be all you need to get closer to the intended result. 

Fusible and sew-in aren't always quite the same

Even when two products seem very similar, whether they're fusible or sew-in can change the feel of the finished bag.

For example, I find the fusible versions of Peltex, such as 71F or 72F, generally give a slightly crisper and more structured result than the sew-in version. Once fused, the fabric and stabiliser behave more like one layer, so the finished bag can feel noticeably firmer even when the stabiliser itself isn't dramatically heavier.

What if I deliberately want an even firmer bag?

If you've followed the pattern recommendations and simply prefer your bags more structured, I usually recommend making adjustments to the exterior, rather than adding extra stabiliser to the lining.

Depending on the particular pattern, adding another layer or two of woven fusible interfacing to the exterior fabric or choosing a slightly firmer stabiliser may give you the result you're looking for.

I wouldn't automatically jump to a very heavy stabiliser, though. Firmer isn't always better, and too much structure can make some bags difficult to sew and turn, or cause unwanted creasing in areas that need to bend.

For your next bag

If you'd like your next bag to look as close as possible to the pattern sample, start by following the interfacing and stabiliser recommendations in the pattern. Those are the materials I've chosen and tested specifically for that design.

And if you've used the recommended materials but your result is still much softer than expected, please feel free to contact me. Let me know which pattern you made, what exterior fabric you used and the exact interfacing and stabiliser you used, and I'll be happy to help work out what may have caused the difference. 😊
