Drawing directly on to the updated toile with a friction pen I could mark and erase as many times as I liked to get just the look and proportion I wanted for these different elements. I was then able to trace these new lines to create new pattern pieces I needed, adding back in seam allowances where needed.
I will now let you in to a little secret, before cutting my pattern pieces from my denim and lining I made a point of totally mistreating my fabric.
I do this before making up any everyday clothes these days. Both lining and denim went through a 40 degree wash then into the tumble dryer. This way I knew the worst that could happened already had!
(When I first got a tumble dryer a couple of years ago I got carried away and left my perfectly fitted ginger jeans in a wash AND dry cycle without thinking, but that’s another story, you’ll have to check out my insta and facebook feeds to find out how that got fixed!)
