I think it was really cute to start with, the fabric is really beautiful.
And I have to say in response to the post above, her boyfriend telling her that he doesn't like it is in no way abusive. I would be happy if my husband would honestly tell me when he didn't like something. I mean, why do you even ask if you want to be lied to? However his opinion is just that, and you should feel free to ignore him when he's wrong.
I also buy tons of vintage patterns - and almost all of mine are already cut. I think it makes it way easier, I hate dealing with those huge sheets of fragile paper.
Also, I may be wrong but aren't most patterns from that era only for one size? If so you aren't losing anything but extra blank paper by cutting it.
Most of these cut vintage patterns I have were cut by their original owners back fifty or more years ago, and I am still enjoying them today, so cutting it won't necessarily ruin it for future generations!
