I also translated the Portuguese to English, a difficult proposition since this appears to be South American -- probably Brazil - Portuguese, which is a far cry from Portuguese from Portugal. My Spanish Language background was a big help (took it from grades 5 through 12, and then again in college. Anyway, the first line says, essentially: "Look what I did with the pattern by Lynette Anderson!" And the second line says "The quilt makes me want to put the house in order for Christmas now!"
I can understand why the pattern is so expensive, but honestly, the price puts it out of my ability to afford, which is too bad. It's a beautiful quilt!
If you're determined to do this quilt, why don't you design up the squares, and put in the appliques of Christmas that you can do. Personalize it. Embroider family names in some of the squares, for example. If you're mad to do a fancy ornament (which is something I would do), then design and applique it. You may not end up with anything that looks like this quilt, but it would be in the same "spirit" of the season, and it would be unique. That's what I would do.
Good luck to you!
