I've had to get out paper and pencil a few times. Last night i was reading a Fon's and Porter magazine and looking closely at one done in diamonds of lime greens, whites and black fabrics. All of a sudden i had problems with my vision. ended up getting a visual migraine. bright fractals sort of curved. Hmmm. too much staring? i closed my eyes and rested half an hour and it was gone. So too many quilting ideas are not always a good thing.
