Thank you to Vlieseline and for giving me the opportunity to review this product. As a quilter and dressmaker, I’ve never considered making curtains or pelmets for myself or others so when Vlieseline sent me some of the S133 Balear interlining to review for them I didn’t know much about this product or how it was used. We usually know someone who does though, so I popped along to see a friend of mine who does make curtains and, lo and behold, she has used Vlieseline on many occasions. One thing I didn’t realise was that you could press it onto the curtaining in the same way you would use an interfacing/fusible webbing onto applique or neck/button strip facings. I did some research on the web on the Vlieseline web page to find out more about it.

S133 Balear is a heavyweight, firm, fusible pelmet interlining that retains its shape well over time. It is made of 60% polyester (PES) and 40% cellulose. S133 can be sewn too. It has adhesive on one side only – look closely, it’s slightly glossier on one side.

Cutting: a good clean cut was made using a rotary cutter, and scissors work just as well too.

It’s about 2mm (1/10th”) thick and can be hand washed but it is not generally recommended for use in the washing machine.

It takes just 15 seconds with a medium iron to fuse to the fabric you are using. It is recommended that you use a damp cloth between the iron and the interlining when fusing it to your project. Allow the pieces to cool flat for about 30 minutes afterwards. It is recommended that you check the adhesion quality meets your expectations first by testing a small piece of the interlining to a fabric remnant with your iron.

S133 Balear interlining is very versatile as it can also be used in range of creative work such as fabric bowls and storage boxes, bottom and side panels of bags, and even the peaks of caps. In some patterns it suggests that the heavy craft interlining can be used as a backing for magnetic clasps on bags so don’t throw away those leftover scraps just yet!

It is approximately 18” (45cm) wide and the current price range is between £8.00 and £10.99 per metre so it’s best to check around first.

As there wasn’t enough of the sample to make a pelmet with, and because there’s always a birthday, anniversary or other celebration coming up, I decided I would make some gift boxes using the S133 Balear interlining instead. There are lots of free patterns out there showing you how to make a range of fabric gift boxes and I chose an origami gift box made 2 in different sizes. I used the Sewing Mag website for ideas – see link below.

What you need:

Purple Origami Box Cut 2 squares 9.25” x 9.25” – one each of contrasting fabrics.

S133 Balear interlining – cut one 9” x 9” square

Buttons, bows etc to embellish.

Christmas Origami Box Cut 2 squares 12.5” x 12.5” – one in Christmas fabric and one in a contrasting fabric

S133 Balear interlining – cut one 12” x 12” square

Cut 2 pieces of ribbon approx 8” long (I used 0.5” wide red ribbon)

Buttons, bows, to embellish


Cut out your fabrics and interlining using the above dimensions.

On the non-adhesive side of the S133 interlining divide the measurements by 3 and mark accordingly using a pencil. The Purple box will have 9 squares marked – 3” x 3”, the Christmas box will have 9 squares marked – 4” x 4”. Cut the 4 corner squares out and pop to one side (you can use these for other projects).

You might find it easier to score/fold the centre square upwards before you have ironed into place – this will help create a smoother line around the base of the box.

Place the contrasting fabrics Right Sides (RS) together and sew a 0.25” seam around 3 sides of the square.

If you are adding ribbon as a tie for the box (Christmas box) place the ribbon strips at opposite corners on the RS of the fabric. Place the contrasting fabric RS together and sew a 0.25” seam around 3 sides of the square.

Turn the fabric RS out and Press. On your unfinished edge, turn in a 0.25” seam to the Wrong Side (WS) and Press – this will make it easier to sew once you have ironed the S133 Balear interlining into place.

Decide which fabric is going to be the main/outer fabric of your box and lay this facing up – I chose the purple spots for this box.

Position the S133 Balear interlining inside the fabric square like below with the adhesive coating side facing upwards. Press with a medium iron for no more than 15 seconds. It really does not take long for it to ‘stick’ to your fabric. It will feel quite floppy until it cools so try not to move it too much -it doesn’t take long! When it’s cooled slightly you can ‘fold up’ the box into shape and press a ruler or finger press along the folds of the bottom square if you wish. Leave the ‘opened’ edge open until you have sewn around the box outline.

If you look below, you can just see the outline of the box shape in the pic on the left. Using your fingernail or a marking tool score the outline of the box on your chosen main/outer fabric (purple spots). Using your zipper foot, sew as close to the box outline as possible to create a crease line. I used the normal machine foot for the purple box but changed to the zipper foot for the Christmas box and found it gave a more accurate line around the box.

Don’t worry if you sew on the interlining itself – it won’t damage your needle. You can either use a matching or contrasting thread for this.


Sew the ‘opening’ together either by hand stitching or by machine. Optional – you can machine stitch around the outer edge of the box if you wish.

Pinch the edges of the box together on the crease line as shown below and pin into place. This will create four cone shaped pockets on the outer edge. Sew a few stitches at the top to secure the sides.

Fold down the corners to make the flaps, finish with a button, bow or some other embellishment of your choice.


Voila, and they are done!

You can easily change the shape and depth of the box if you want a rectangular gift box or you can make a lid just by using the one of the layouts below.

I enjoyed making these Origami boxes and they are really quick and easy to make. It could be a great way to get children interested in sewing too. The Vlieseline S133 Balear (pelmet interlining) gives it the structure it lacks by just using fabric. It would also work by using the Vlieseline S520 medium weight interlining – I will be writing another review for this later.

Vlieseline also have a pattern and instructions for a storage box and you can find it at the link below. At the end of the instructions there is a link to a pdf for the storage box dimensions too.

Grateful thanks to Vlieseline for supplying the S133 Balear interlining and to for giving me the opportunity to write this review.

Happy Sewing Everyone
