A few days ago I found this video : Pressing tips
It demonstrates how the ham is used and gives some other pressing tips.
In the past I have worn clothes that had that how-made-look to it. That resulted in not wearing them anymore and giving up sewing. I now think pressing with a ham would have made a difference. Unfortunately I wouldn't know where to find a ham, so I searched for instructions to make it myself.
What I found (Make your own ham
) doesn't seem very complicated so I will give it a try.
I'm also thinking of making my own dress from out of paper tape or duct tape. But first I have to re-gain trust in my sewing skills.
