I did just the other day!! I used a template I used to make a complete quilt with a couple of years ago. I was only making one block this time & guess what.......I needed another petal to make it lay flat. I used fabric different than what was already in the plate - something that blended & I have to look hard myself to find it!! I'm leaving it. Still not sure what happened but it has to have been that I used too wide a seam this time.
