I've had the most fun reading everyone's progress! My patterns finally arrived this week too, so I was able to get started. Here is my trouser, McCall 4803:
First order of business was tracing and grading the pattern since the waist on this one is 26" and I haven't personally seen a 26" waist (at least not on my body!) since 1987.
I created a little tutorial on how I grade up pants (and skirts) on my regular blog, Quality Time. You can go read the tutorial there if you'd like!
As a plus-size vintage lover, I've had to invest lots of time to little tricks to use these lovely patterns that, more often than not, are way too small.
Now I'm off to muslin!
