Drafting a hem that is longer in the back then the front is slightly more complicated than one would originally think. That’s what the hubby let me know on Friday night at least.
The simple way to draft the hem is to mark the front, the back, then draw a straight line connecting the two as illustrated in the diagram to the right.
However, when done this way the angle of the hem starts centre front and doesn’t allow for a gentle curve. Which is exactly what is wanted/needed.
So, my hubby, brilliant at maths, pulled out equations he uses at work on occasion and calculated how to gently slope my hem for me.
It involved a fair bit of trigonometry (something I haven’t glanced at since grade eleven), plus some advanced trigonometry I’d never used.
When he explains it to me better than he did Friday, I’ll post up the steps for anyone that would like to draft a sloping hem of their very own.
Needless to say, every 4.75″ I’m marking my hem down a little further.
Thank goodness only the top tier has to be angled!
