I did a bunch of stuff to try and get the rust out. I tried to write it out, but it really is a long boring story. The end result is the best part.
But in case you were wondering, this is what I think helped the most and what I would do first if this were to ever happen again (which it won't because I learned my lesson):
My precious sweater is now blocking. And I don't want to speak ill of Starsky after the horrible ordeal it has just been through. It was an innocent bystander in an ongoing battle that is larger than Starsky can comprehend. But is it my imagination or are those sleeves the largest sleeves EVER? I know a bit of that can be explained by camera angle, and I know that the sleeves are longer than usual so you can cuff them. But is it meant to have eight inch cuffs?
We'll just have to see how it looks once it is all assembled. Right now I don't want to subject Starsky to any more unnecessary trauma.
