I love pockets. They make me feel very very happy. All my favourite pieces have pockets and I always try to include them in my patterns when I can. They are handy for keeping things safe and keeping my hands warm!
Adding pockets to a seam is a very quick and easy process (both pattern cutting the pockets and sewing them) and once you have a pattern you are happy with, you will be able to use it over and over again, with minimal changes.
If you think you would like to add pockets to the next garment you make, then check out the tutorial.
