Hemming Lightweight Fabrics With a Serger & Sewing Machine

Maura Kang

We’ll show you the easiest way to make a rolled hem on chiffon fabric, or any other similar lightweight material. We’ll first demonstrate it on the serger, then with a domestic machine for those who don’t own a serger. Using the recommended materials and this technique, the result will be a beautiful rolled hem that looks just as professional as if it came from the store!

A lot of formalwear uses sheer, lightweight fabrics, and this method is a good way to keep the edge looking professional like it had never been modified. Apart from your machine, you’ll only need some small but important materials:

First, you’ll want to choose the right thread. We’ll be using a 100wt poly thread called InvisaFil, which is going to blend really well in the fabric so you don’t even see it. And because the thread is so fine, it will stitch more easily through the thin fabric, resulting in fewer ruffles. It’s important to use a very fine thread like this because apart from showing less, it also won’t weigh down the lightweight fabric either.

Because the thread is so fine, we’re also going to choose a needle with a smaller eye. Choose a size 60/8 or 70/10 microtex needle which works best on light fabrics.

Finally, I’m going to use a bobbin that’s been pre-wound with DecoBob thread. This is an 80wt poly thread that comes already pre-wound on a plastic sided bobbin which will pair well with the top thread. You can alternatively wind your own bobbin with the InvisaFil thread, just remember wind it slowly since the thin thread tends to float away. If you’re going to hem your fabric on a serger, obviously you won’t use a bobbin so you’ll want DecoBob thread on a spool for your lower loopers.

On a Serger: 

We are going to use a 3 thread rolled hem, with InvisaFil in the needle and upper looper, and DecoBob in the lower looper. Consult with your serger manual and adjust the stitch length and cutting blade to get a close narrow hem.

Once your machine is threaded, do a test run on similar fabric to make sure your fabric is not puckering. You may have to adjust your differential settings to get a flat, smooth edge. 

Mark your hem with a disappearing marking pen, and serge exactly along your marked line. This is the simplest method for a quick fine hem on chiffon or similar fine fabric.

On a Domestic Sewing Machine With a Rolled Hem:

If you want to hem fine fabric on a domestic machine, this two step method will help you achieve perfect results. Mark where you want your finished hem and cut 1” below the marked line. We will trim this closer later. Be sure to spread the fabric out flat and even as these types of fabrics can easily shift during cutting. Thread your machine with InvisaFil on top and DecoBob in the bobbin. Now you’re ready to sew!

7.png

Using your fingers, tuck the edge of the fabric over 1/8” below the finished hem length and stitch very close to this folded edge. Do this all the way to the end of the fabric. If you’re hemming a sleeve or skirt, or anything where your piece is a loop, we recommend starting and ending on the seam to help hide the backstitching.

8.png

When you’re done, use a pair of sharp, fine tipped scissors to cut away the remaining fabric as close as you can to your line of stitching without snipping into the stitching itself. Exercise caution so you don’t accidentally snip over your seam. Do this all the way to the end.

9.png

Press all the way around to sink the stitches into the fabric and smooth any puckers.

10.png

Once you’ve finished trimming the excess fabric and pressing, tuck the edge 1/8” over one more time (along the finished hem marking) and stitch it down again over the original line of stitching to complete your rolled hem. If you have trouble tucking the edge over with your fingers and keeping the 1/8” length consistent, you can press the edge down with an iron before sewing.

That’s all there is to it! You can see how little the thread shows in the finished hem as well how flat the edge sits because the fine thread doesn’t add extra bulk. As most hems have a curved edge, doing the hem in two steps helps keep your hem even and consistent and eliminates any problems. These materials combined with these simple techniques are all you need for perfect, professional hemming.

Easy Serger Blanket Stitch Tutorial

Maura Kang

Here’s a super quick and easy tutorial on how to make a quick machine “blanket stitch” edging on your serger. A two-thread flatlock stitch and some water soluble stabilizer will produce a beautiful, hand finished look. It’s a great way to finish blankets or other projects with this incredibly fast and simple serger solution.

Let’s start by setting up the serger. You will need a serger that has the capability to do a 2 thread flatlock stitch. Most sergers are able to do this, so check your manual to set up your machine.

1.png

A bold thread will have the best effect for this stitch, so we’ll be using a 12wt variegated cotton called Fruitti in the needle. This thread has been double gassed, resulting in a very low lint finish, so the stitches will look clean and beautiful when it stitches out. Another option is 12wt Spagetti which is the same thread as Fruitti, but comes in solid colors.

2.png

You’ll need a 90/14 topstitch needle in the serger to accommodate the heavier thread.

3.png

In the loopers, we’ll be using this medium 50wt cotton thread called Konfetti in a colour that matches the blanket. The finer weight works well with the heavier Fruitti thread.

4.png

For the blanket, we’re choosing this cotton flannel which is warm and soft to the touch. You can choose to do a single layer, a double layer, or a double layer with batting in the middle. Be aware to follow fire safety regulations when choosing fabric for babies.

5.png

Before you begin, cut a length of water soluble stabilizer long enough to go around the edge of your blanket, with a width of about 3 inches. You can use pieces so you do not need one continuous length.

6.png

Set up the serger to do a 2 thread flatlock stitch, with a wide cutting width. Place a strip of the wash away stabilizer along the right edge of the blanket and stitch along the edge of the fabric. The stabilizer will lay on top of your project. Continue around the circumference of your blanket, making sure the knife of the serger is cutting off a small strip along the edge as you sew.

7.png

When you have finished going around all four edges, remove your work from the serger, leaving a tail to finish off.

8.png

Tug on the wash away stabilizer all the way around to pull the stitches to the back and leave a “blanket stitch”. Trim the stabilizer close to your stitching, taking care not to cut into your serger threads. Rinsing the finished project will remove the remaining water soluble stabilizer.

Weave the thread ends into your edging using a large eye needle. A drop of fray check will prevent them from unraveling later.

11.png

If your blanket is rectangular, you will go off the edge at each corner. After you have finished your piece, you will need to go back and weave in the serger threads at each corner to finish.

If you make the corners of your project a slow curve, you will not need to finish loose ends at each corner. In this case, begin your stitching line along one edge, not on a corner. When you come to the end, you will need to overlap your starting stitches, then slowly edge your way off the fabric, trying not to create a ‘point’. You will have only one set of loose threads to weave in.

12.png

And that is all there is to it! In minutes you will have a nicely finished blanket! This is perfect for making receiving blankets for babies, a simple blanket for yourself or your family, or quickly finishing the edges of a project off.
