There is nothing wrong with the blades that a good pressing won't cure. You will have to fudge a bit when you applique them to the background because some of the blades will overlap each other a little bit. If there is too much overlap, blind stitch it down. No one will ever see it once it is quilted.
My pattern makes 20 blades. Dresden templates come with several different degree angles, so the number of blades is different depending on the angle. It doesn't matter as long as the hole in the middle is 360 degrees. Don't fool with trying to get the ends of the plates in the hole even. That doesn't matter since you will be covering it with a center. Dresden is my favorite block, although I make the blades with points.
I don't have the patience to do the lovely and more feminine round--topped blades. froggyintexas
