I see so many helpful suggestions for borders, colors ect that I would not have thought of. It is nice to be able to have a place to ask. If the person posting does not want suggestions, just post and say "Look what I made!"
On the other hand, if you want suggestions, there are many who are willing to help. The colors I like together might put many off, but I do not care if they do not like the combos, so I don't ask. I am making a lime green, pink, yellow, turquoise, purple and black quilt now. I didn't ask, I don't care. On the other hand I might find someone with a WAY better idea for some block selections, so I would ask!
I really do not see malicious comments, but helpful suggestions and lots of laughs.
