Daughter Jessi chose this  Helios pattern with coral and white fabric for a new quilt.  Went together quickly.  I knew I needed to quilt it with straight lines.  On the longarm, straight lines are difficult for me.  So I forced myself to use a longarm ruler.  Marked the lines in the squares first and then used the ruler.  It worked well.  I did get better as I went along.....practice!!!
