As the Sydney weather has suddenly taken a quick trip south in temperature, I need tops desparately so the other Saturday instead of going to one of the two ASG Groups I go to I bit the bullet and got stuck into this job.
It took me most of the day because I probably do it a lot more labour intensive than it needs to be, however this system worked for me.
I now have 7 t-shirts that are the correct length.
The amount I shortened these t-shirts varied by brand ranging from 5cm to 8cm and that is not including the hem amount.
I have also made a note in my notebook of how much to wind on the bobbins for each hem as I'm sure this will be a job I have to do again.
