I agree with many posters here today, why on earth would it be okay to send an "ugly" quilt? If I have a fabric that doesn't makes a quilt ugly then it doesn't go in the quilt. Also, what is considered ugly in america might be perceived very differently in another culture.
As far as the group goes, if you are new you might not want to get into the fray on this one. In the big picture of things try to remember why you are making the quilts in the first place, to do something good for someone in need.
