Materials Science: Sewing with Bosal

Materialkunde: Mit Bosal nähen
After stumbling across it on English-language websites more than once, I did a little research and found out what you can sew with Bosal. In this post, you'll learn everything about this great material!

Sewing with Bosal: But what exactly is Bosal?

I only recently discovered it myself. I became curious because many American bag makers use Bosal to reinforce their creations. Now I've found out that this brilliant material is also available here! Bosal* is a foam-like volume interfacing that is adhesive on both sides. It keeps the fabric beautifully smooth while also providing good padding. Sewing with Bosal  

How is Bosal used?

Bosal is ironed between two layers of fabric. It sews very well and holds its shape. By the way, it's a great tip for bag makers!

Is there a trick if I only want to iron Bosal onto one piece of fabric?

Yes, there is! While you iron one side of the Bosal onto the fabric, place parchment paper on the other side. After it has cooled, you can simply peel it off. Alternative: Iron a thin, inexpensive cotton fabric onto the second side and use Bosal like a normal interfacing.

What does Bosal look like?

The soft but firm foam interfacing is approx. 3 - 4 millimeters thick. It is cream-white and has a fine plastic texture on the top and bottom that melts when ironed. This bonds it to the fabric, making it very stable. Sewing with Bosal  

Where can you order Bosal?

I order it from Amazon*. However, you should be prepared for the fact that this cool stuff has a delivery time of around 2 weeks. So order early when you're planning your next bag project. It comes in large pieces of 45 x 145 cm and costs around 10 euros. *  

What makes Bosal special?

Bosal is similar in properties to Style-Vil* by Vlieseline. But unlike Style-Vil, which you have to sew in, Bosal is simply ironed between the outer fabric and the lining. Sewing with Bosal

What do you need to pay attention to when sewing with Bosal?

Very important: Reinforce the fabric with Bosal first, THEN cut it. And: The fabric must cool down completely after reinforcing. If you insert sewing pins or use fabric clips beforehand, small bumps can form. The cooled fabric can be sewn with a completely normal needle (size 70 - 80 is sufficient!). However, Bosal is not suitable for sewing with the wrong side facing up, because it bonds the outer fabric and lining together. Sewing with Bosal  

What can you sew with Bosal?

Bosal is very suitable for bag projects. For example, I also reinforced my Tablet Bag with Bosal and am super happy with the result. Big plus: It sews together fantastically.   Sewing with Bosal   Bosal is also very suitable for Tablecloths :Sewing with Bosal   Our Bag Organizer Versailles also becomes nicely structured yet flexible with Bosal:Sewing with Bosal  

Can you wash things sewn with Bosal?

Of course! I washed Bosal at 40 degrees and it held its shape very well. However, it should not be dried in the dryer. I dried it flat - it worked great!

Ich komme aus Siegen-Wittgenstein, wo ich meine Kindheit damit verbrachte, Kühe einzureiten, von Heuhaufen zu hopsen und in “Handarbeiten” eine 4- zu kassieren.

Kreativ zu sein empfinde ich heute als unbeschreibliches Glück – das sich noch vermehrt, wenn ich es mit anderen teilen kann. Seit 2016 feiere ich auf diesem Blog meine Nähleidenschaft und freue mich, dass das Nähen so viele Menschen verbindet.
