Beautiful quilt -- your design and colors are wonderful!!! If the straight lines bother you (I know if something about a quilt bothers me I can't get past it), I would audition the changes first since sometimes I find I like the original way best. I have been arguing with a quilt for a couple of years -- it says it is a wall hanging and I say it is a lap quilt and so far nothing I have wanted to add looks good when I audition it.
