I figure any advice offered is neither good nor bad, its just advice! I make the assessment and decide which advice to take and which to ignore. I also try to always politely thank the advice giver, even when I know that I am never going to follow up on the advice. If I am unsure of something, like what needle to use, then I listen, and try to some research on my own ( bless the internet!). I find that advice is mostly offered with good intent, and a desire to help. So a simple "thank you" goes a long way toward keeping the peace at the fabric counter! (Works with my family, too!)
