Good morning! Today we want to introduce you to our latest acquisition: Decovil I, a semi-rigid, fusible interfacing that will open up a whole new world of possibilities for you, just as it has for us. We’ve already tried it and love the result, with a very professional finish, and we’ve come up with tons of things to make with it. Keep an eye out, because we’ll surely be using it in a tutorial soon.
Why Decovil I?
Although there isn’t much information about it in Spanish, we had read tons of praise and positive opinions about this interfacing on many English-language blogs. Because of its texture, it allows you to give projects a degree of stiffness that can’t be achieved with batting, for example. It’s used to make bags, hats, wallets, bags, baskets, briefcases, belts, and all kinds of accessories.
Features and advantages of Decovil I.
- It’s fusible. In other words, it bonds to the fabric with the heat of an iron.
- It has a leather-like appearance and is very flexible, which makes it very easy to work with.
- It can be perforated or, in other words, is suitable for sewing.
- It doesn’t tear, fray, or break.
- It’s elastic and dimensionally stable, foldable and firm at the same time.
- The corners and edges are practically indestructible.
- When applied to fabric, it leaves no bubbles or wrinkles.
- It can be ironed and washed, either in the washing machine (at 30-40º) or dry-cleaned.
How do you use Decovil I?
You already know that fusible interfacings have one rougher, shinier side, easily recognized by sight and/or touch, which is the side with the adhesive. This is the side you need to place against the fabric to secure it.
- Press the fabric you’re going to use with steam to prevent wrinkles. Let it dry completely before joining it to the Decovil.
- Place the rough side of the interfacing against the wrong side of the fabric (that is, the side that isn’t the pretty one). Align the edges so it’s perfectly positioned. Remember, we’re going to bond it!
- Place a damp cloth over it and press slowly over the entire surface, pressing for about 6 seconds so the adhesive can activate. (Recommended iron setting: wool.)
- Let the adhesive set for half an hour without folding the fabrics.
- Time to sew!

Important notes and tips.
- Keep in mind that Decovil is fairly thick and very substantial, so if you’re making a project that needs to be turned right side out, remember to leave an opening that’s large enough.
- Depending even on the type of project, it may work better for you to sew the outer fabrics together first (top + bottom), leaving an opening, and insert the Decovil once you’ve joined them. Precisely because of its stiffness and substantial feel, as long as you leave an opening wide enough to maneuver, you can insert it afterward and, once it’s inside, proceed with ironing, bonding, and sewing.
- As we always advise, it’s better to be safe than sorry, so before you start working with it, you can make a small test on the fabric you’re planning to use.
Laura has already gotten her hands on it and is delighted with the result: impeccable! For its debut, she chose that lovely case in the photo for her sewing supplies :) She ran it through the sewing machine without any problem, and if a little wrinkle or fold appears while you’re handling it, you only need to run the iron over it to make it disappear.
