I would like to start a DJ quilt. I decided on white for the background and bought a 15 yd bolt of white on white. Will this be enough? I also have 7 yds of another white on white and they seem to match. I have the book and the software. I love purple and decided all the blocks would be white and purple. The problem is I love red too. Do you think I could use red as the cornerstones in the sashing? I seem to be intimidated by the DJ quilt for some reason. I guess I read about so many DJ quilts that took years to finish.
