Okay, take a deep breath and exhale slowly. Go eat chocolate. Have a nice cup of coffee/tea, or a cold drink. Put your feet up for 30 minutes and stroke cat. Listen to soothing music.
NOW you can return to that blasted quilt and not be angry enough to throw it at the garbage man. Repeat after me...as Zaza Gabor said "i've never hated a man enough to give his diamonds back to
him." So you should never be mad enough to hack up a lovely quilt or to hide it in the closet for the next 10 years. Remember, any quilt made well is welcome to those who don't have any, no matter what color, pattern or fabric.
