To make a pig’s ear of something!

Make a pig's ear“Make a pig’s ear of something” means “to do something badly”.

For example: As I am not a very practical person and definitely lack basic d.i.y skills, I always make a pig’s ear of painting, decorating, fixing the washing machine, hanging  pictures and assembling anything that I might have bought from Ikea.  How about you, what do you make a pig’s ear of?
