Tracing a pattern off a top

After making a top from a pattern that turned out way too big (in class), I decided to try and make a pattern from one of my best fitting tops. Here it is, in possibly the grainiest photo on the internet:

So I laid the top flat, and pinned some tracing paper onto it...

Then traced the seams...

Drew some alternate necklines...

Lengthened it so I could make a dress out of it too...

Then cut it, folded it in two and checked it against the top again to correct the seams a little...

I did the same thing for the back, and I had a pattern!

For the sleeves, I traced the front and back on paper separately...

Then joined them and retraced them on some new paper (this worked because my sleeves had some gathering, I'm not sure it would have worked otherwise).

Then a band for the high neck version, and I was good to go!
