This is, by far, the most embarrassing page I've ever had to write.
You see, I failed to take my own advice.
I've written over and over about the importance of fit when creating a block pattern. Fit, in fact, is the reason you draft a block - once you have a perfectly fitted block pattern, all of your normal alterations are taken care of. You'll have a sleeve of the correct length, a bust dart that fits your figure - you won't have to keep shortening sleeves on everything you ever make.
That is, IF you go through the fit process thoroughly and correctly. I didn't.
A couple of years ago, I drafted a new dress block. From that, I made a blouse block, from which I made a blouse.
It didn't fit well.
I mean, I THOUGHT it fit (or at least, it fit well enough) - so I just stopped working on it and thought it would be OK.
Until I made a blouse. And almost never wore it. Because I knew it didn't really look good.
So - this video explains what happened, and what I had to do to fix it.
PLEASE learn from my mistakes! Take the time to fit your block properly before using it! (and if you're just tired of the whole process - which is part of the reason I didn't follow through - just set it aside for a few days to rest your brain!)
