I am with a volunteer group that brailles books for children as gifts. We are all sighted. We have a book already done in Grade 2 braille and now someone has requested that they receive a copy of the book done in Grade 1 braille. How do I convert the file from Grade 2 to Grade 1? This particular book happens to be 5 Grade 2 volumes in length. I know that the amount of pages will change and the title sheets will have to reflect that. Also, is it necessary to do Grade 1 double line spaced or is that only done if requested by the person receiving the braille book? Barb
