Pillowcase - easy make

 You'll need a piece of fabric. 

You may use cuttings from another project, or old cloth. If you decide to buy new fabric, my advice is to seek with such a manufacturing defect. Is cheaper and will give an interesting effect on the pillowcases.

Measure the pillow. 
In my case - 40 cm wide and long about 40 cm.

      Cut the fabric with size:

         Width:  40 cm + 2 cm reserv.

          Length: Two and a half times the length of the pillow + 2 cm reserve.

       Bend the two short sides on sewing machine, or use hand sewing needle and thread.

   Fold in the form of pillow. The piece, having a size half the length of the pillow, should be on top. So when you turn on the pillowcase, this piece will stay inside.

Sew the two sides which are not sewn. Turn so that the edges stay inside.

You're ready :)
