Is this normal? Come on, no one has been honest...of course it is not normal!!! Who in their right mind would take perfectly good yardages of fabric (after taking who knows how long debating whether they 'go together' or not), spend hours cutting them into teeny tiny pieces, and more countless hours sewing them back together and then, for pete's sake, consider doing in again, not once, but time after time, year after year. We quilters have a strange malady and the rest of the world is just going to have to accept that this bit of insanity is what keeps us right with the world in other ways.
Enjoy whatever obsession you have at the moment. (By the way, the photo you posted of your quilt is lovely! Keep up the good work and don't worry about enjoying the same thing over and over.)
