If I see a ketubah that I like by one artist and a text that I like by another, can I order it that way?
Yes and no. Modern Hebrew texts and English texts will vary from ketubah to ketubah and are not interchangeable since ketubot have already been printed and most artist's languages are copyrighted. Some artists will allow their texts to be used on another's design, but there usually is a fee attached. In addition, you would have to pay for a 'blank' ketubah and for the new text to be written in as a custom text.
