What is the way to do this? I usually export the instance and add as master as font.
You can do it directly via the Plus menu in the bottom left of Font Info > Instances.
Cool! it would be nice as a right click on instance item
Hmm not sure. It is hopefully not something you do often.
I do to refine a good interpolation or extrapolation
I strongly suggest to not to add too many mastes. Instead, refine the masters. And for glyphs, that really need some adjustments, you can use brace layers.
Yes, I know… I usually draw the regular/medium master, then a thin/light and make the black/bold using an instance. I then convert the instance to a master and I must refine it.
How many masters do you have in the end?
- But I think I can reduce to 2
