i don't think i would ever look at someone else's quilt picture and point out what i thought was a mistake- unless the person asked- something just isn't right but i can't see it---
if it is all finished and they are happy enough with it to share it i would never be so presumptious that my design thoughts should match theirs--or is the 'right way' and theirs is a wrong way=
all of my quilts have plenty of mistakes- sometimes i see them & fix them- sometimes the quilt is all done & i notice it- and leave it- it is the (personality) of the quilt...if i am having a problem i'm not afraid to ask---what is wrong with this? why is this not working? but if i make a quilt- finish it and believe it is as it should be i would be pretty *stunned* to have someone start picking it apart and telling me i did it wrong- not that it has never happened- i've ran into my share of (self-proclaimed quilt police) over the years....but i would never consider doing such a thing to a fellow quilter.
