Sound, healthy sleep is the key to our health. It largely depends on our bedding, which should be clean and comfortable. Very often, during sleep, the sheet slips, wrinkles and causes discomfort. The main reason is the small size of the sheet or poorly tucked sheet.
I realized a long time ago that the length of the sheet should be such that it can be tucked under the mattress 15-20 cm on each side. To do this, you should add fabric and lengthen it.
You can also buy special fasteners with elastic bands; they tighten the sheet at the corners or along the entire length of the mattress. If the sheet is too small, then sewing an elastic band that tightens the corners will solve the problem.
Another option is to purchase or sew sheets with a circular elastic band. There's a great replacement here.
I show you a new type of non-slip sheet.
First you need to measure the width, length and height of the mattress. For me it is 140x190x17 cm.
Now we calculate how much fabric is needed.
Draw the length and width of the mattress. On 4 sides we add 17 cm (height of the mattress). We also add 4 cm for allowances on each side.
In the corners we mark squares 21x21 cm (17+4cm).
If you are altering your sheets, add another suitable fabric that is missing.
I made my sheet from a duvet cover. There is still some fabric left for pillowcases.
1) I folded the finished sheet 232x182 cm in four and cut out squares in the corners, leaving room for allowances.
2) I folded each corner and stitched it right side out, then turned it inside out and stitched it again. The result is a closed seam.
3) I folded the edges of the sheet and stitched them in a circle.
4) I folded the cut out squares diagonally and stitched them, leaving room for turning them inside out. The result is triangles.
5) I stitched them onto the corners of the sheet.
6) A new sheet, just like a regular one, can be folded evenly, you just need to practice.
The sheet fits the mattress, and the triangles prevent it from straightening out during sleep.
All the best!
