How to sew a fitted sheet (from 100% silk fabric)
Recently I visited Canada, and one of the main Canadian fabric stores Fabricland was relocating and having a big sale. So I bought 6 meters of this nice 100% silk fabric for 10 Canadian dollars per meter (not a yard! Regular price was above 30 dollars). It was called Sangria silk and had all the properties of mediumweight silk Shantung.
The print on the fabric obviously suggested that it is not for garment sewing – it is a decorator fabric, and probably bedding. The fabric is durable (silk fiber is one of the strongest natural fibers), suitable for heavy use, washable and it is easy to sew.

And here is the result of my work. I think it looks great! And how it feels? Oh, it is the nicest sheet I ever had!
By the way, I have so many flat sheets just sitting in my closet. I never use them because they are always sliding off the bed and I hate to tuck and readjust them all the time. Are not you the same?
So let’s proceed with making the fitted sheet.
Please note that measurements in this article are provided in metrics so if you are used to working with the imperial system please use this chat from www.craftsy.com or this chat from www.ludlowquiltandsew.co.uk.
Step 1. First you have to measure your mattress:
- a – length
- b – width
- c – height
After all, mattresses are different: for babies, kids, twin, queen, king, full, double, etc. Plenty of people have non-standard mattresses (in RV for example). So you need to know the measurements for your particular mattress if you want to fit the sheet properly.
I have a pretty standard queen mattress and its dimensions in cm are these:
a = 200 cm b = 150 cm c = 25 cm
Pre-wash the fabric. If we are going to use it for bedding it has to go to the washer regularly. Before pre-washing I had to serge (to finish) 2 raw edges (other two are selvages, they don’t unravel) because the silk fabric is fraying a lot and if you pre-wash in the washing machine without finishing the edges first you will lose quite a lot of fabric in both ends. So I pre-washed it in warm water for 20 minutes (so it will not shrink later) and let it dry outside (not in the dryer). After that I ironed it with a steam iron.
Let’s cut the fabric. Before that, we need to square the fabric if necessary; please refer to my article “How to cut fabric perfectly straight” for a short tutorial. So you know your mattress length, width and height. Look at the figure below how you should have your fabric cut.
The 4 blue rectangles are necessary to cover sides of our mattress and c1 is equal c plus 15-20 cm (this fabric will go under the mattress).
The final rectangle should be this size:
Length – a1 + c1 + c1 (in my case 206 + 40 + 40 = 286 cm)
Width – b1+ c1 + c1 (in my case 156 + 40 + 40 = 236 cm)
My silk fabric was not wide enough for this size of the mattress so I had to make a seam in the middle.
For queen mattress my measurements were these:
Length – 286 cm
Width – 236 cm, but as I didn’t have wide enough fabric, I had to cut 2 pieces of 118 cm.
And I had to cut 4 square corners with size of c1 (in my case it was 40 cm)
Let’s proceed to sewing itself.
For the middle seam I used a so-called flat felled seams. But I do them a little bit different than I found in available tutorials. So I had to make a new tutorial “How to sew flat felled seams on silk fabric (the easy way)”.
Pin the fabric right sides together (wrong sides out). Stitch 7 mm from the edges with stitch length 1.5-1.8 mm for silk fabric.
Now we need to sew together corners. For stronger and nicer corner seams I used also this flat felled seams technique.
Now we need to attach elastic to the edge so our sheet will fit around the mattress. There are 2 ways of doing it – attach it all around the sheet or attach it only at 4 corners.
I decided to sew elastic all the way around, it seems to me it fits nicer this way.
But attaching elastic is not really an easy task if you never did it before though it is a very useful skill. We need to attach elastic when sewing skirts and pants, etc.
You will need to mark the positioning of the elastic on the sheet edge. For this sheet you need to mark 16 notches with equal distance between them. For this fold the sheet in half lengthwise – mark 2 notches with sharp small scissors, then fold again in half – mark another 2 notches, fold in half again and mark 4 notches, fold again and mark 8 notches.
Take elastic about 5-8 mm wide which is not very stiff and stretches easily. The length of it should be around 3.5 meters (about half of the all around measure of your mattress (2 a + 2 b))
Sew elastic ends together and now mark elastic with 16 pins (or mark it by a pen) with an equal distance between them. But this distance will be much smaller than on the sheet itself.
Pin elastic to the sheet edge at all 16 notch marks lining up top edge of the elastic with raw sheet edge.
At the beginning attach elastic to the sheet with a couple of stitches and after that pull elastic very tight while you attaching it to the sheet.
After you finished sewing the elastic turn the sheet edge with the elastic in and stitch all around with regular straight stitches (length of the stitch can be 2.5 – 3 mm) stretching it while you sew and keeping it flat. After that turn it in one more time and topstitch again.
So if you are not sure you can do it properly you can just make a casing for the elastic all around the sheet edge.
For this fold unfinished edge under about 1 cm and then again 1.5 cm and sew around with a straight stitch. Insert the elastic with a safety pin, sew the ends of it together and close the hole in the casing.
Ok, now the sheet is ready and we can put it on the mattress.
