And this is the newest DIY I tried which is
Making a pair of shorts from an old pair of jeans and it works perfectly !
Let's see the instructions ->
First Get an old pair of trousers/ blue jeans
Then draw a line diagonally like shown in the picture
(take any measurement you like from the waist to the thigh)
Chose the length you want wisely, leaving a few inches to fold and sew the bottom end of the short
Then Cut the trouser using a sharp scissor
After cutting, fold a little section from the bottom of the short upwards and sew it for the short to look better.
And then you are done !
Try this at home as it is really easy.. But make sure to get a good needle when sewing as denim cloths are so thick and hard : )
And you will make a nice home made short
