I have had the same problems with quilt patterns and also with sewing patterns. The big problem is, in my opinion, you have to remember these companies save a bundle of money if they go to a non English speaking country to have them done...Well, having spent some time in China and other places.....translation is a horror if they have no idea what you're talking about and have no word to translate to.... This is soooo sad that we have to "translate" for ourselves.
Another problem is this...No proof readers! No one ever has a proofer anymore and if they do, they don't understand the quilting language! Consider this as well!
