Been there!! Hubby helped me sandwich all the pieces, looked perfect. Queen size. I tied the whole quilt, 4 inches apart. Just so pleased UNTIL I turned it over. Growl, hiss! There was a wrinkle running from one corner diagonal to the other corner. I told hubby I need space for a few hours, wasn't his fault, just happened. I then took all the ties out. Didn't touch it until the next day. Do-over and it was perfect.
