I am making this wall hanging for my sister (my second attempt) and I keep running into the same problem. Because I quilted the center panel quite extensively around the flowers, etc. the wallhanging has pulled to the middle. So I have this funny shape to the panel. I didn't notice it until way later and I am so disappointed as this was quite a pricy investment and i already ruined one. Is there anything I can do to stretch the middle out? any other suggestions or is my only solution to pull out my seam ripper?
