Hi There! Welcome to my blog! I goanna share with you another project which I did recently.

So, I did watch some videos tutorials from others and I decide to make one myself. And I wish to share around my work too! It’s not as easy as I thought to sew a laptop case.

I can say the hardest part is when I sew the stitches which turns out not really nice. And what I did was I sew 2-3 times, so it became like 2 sewing lines. This are the skills you need to learn and do it yourself and see how it feels or looks.

After sewing a few times using sewing machine, I felt that sewing machine is definitely nicer than hand sewing, especially for big project like laptop case. Pencil case not really! Cause it more for beginner, so it would be nice if you practice start from sewing a Pencil case.

Material needed:

Step 1:

Fold your fabric into half to a long rectangle shape.

I align my main fabric which you want it to be the front, and second layer is the fleece, and lastly the lining.

There are a few type of fusible fleece, they have the Iron on ones, Thermoweb Heat N Bond High Loft Iron On Fusible Fleece White 20″X36″ 3339 (4-Pack), Pellon PLF36 Ultra Lightweight Fusible Interfacing. Can use to make your project stable, because fabric is kind of soft and turns out to be no support, won’t look nice too without the fleece. With the fleece it looks elegant and more stable.

Step 2:

Next I iron a bit for both side to make it neat for the fabric.

Measure your laptop with the fabric, then cut the shape out to a long Rectangular shape. You may need to cut slightly wider, to make a seam allowance later on. leave about 1″ inch more for the seam allowance.

Once you measure, use a fabric marker to mark out the sewing area that you want to sew later. To prevent for sewing slanted lined. Its good to mark it out.


Before you sew, turn the fabric to the wrong side and sew. Sew straight up all the way. (The image show I did not sew straight up, So Just sew all the way up will do.)


So it’s turns out to be like that 😦 but it good to practice more and get rid of the sewing machine. Now I know a bit on how to use the machine, you just have to use your two hands, one in front, one behind to control the fabric. start from slow speed on your machine. Slowly slide thru the fabric, and you will get a straight line stitches. Use the measurement on your sewing machine so that you know how many inches for the seam allowance This need more practice for sure!

I’m used straight stitch  all the way. To make it more secure, you can do a reverse/ backstitch  on the starting and ending point. Means the area that you goanna start stitch and the ending.


I did a envelope laptop case, which I think it easier then the zipper case one. Maybe for beginners should be okay.

For the Triangle top is for the case cover, just like a envelope shape.

Step 3:

After you sew the sides, next is the top part for the cover.

Measure about 10″ From the laptop pocket top, mark it out. Fold to half horizontal. Facing the lining side. Then sew a line thru and cut off the excess.

Once sew and cut off, flip thru and you will see a triangle.

Now you can see the line that you sew is the middle line from of the triangle from the picture.


And you are done with the sewing! Lastly, just add a button.

Step 4:

For the button I use a magnetic ones. Is like the magnetic clip. Locate on where you want to put, make sure its balance. Put your laptop in and try it out and you can sew it once you are sure with the alignment. Use a marker to mark out so it’s easy to sew. No worries about the marking, it will cover up once you sew in the button.


And Tadah! Pink Polka-dots Envelope Laptop Case. Now I have my own case, I can bring out easily.

Make your own simple envelope Laptop case!



I totally love it even thou the sewing line not really nice, but anyway is in the inside so not really that obvious also. Ha Ha!

Hope this guide helps you! If you have any question, can feel free to ask me in the comment! I will be glad to help you out.
