Didn't actually cause me pain or problems but I took a class with a well known quilter. He taught a 2 day workshop on his water color fabric painting technique and sold us his patterns. Most of the students wanted to put their own twist on this (including me). He flat out told me that my idea was not to scale (ever hear of folk art?) and was no good! Well...I NEVER! I put that project away for a looong time cause I was so angry at someone I had idolized. Well...a Pat Sloan, finish it up challenge made me bring that out and finish it. I ended up loving it and earning some ribbons for it (in spite of the rough start). Anyway, I learned #1: do not idolize others (my work is just as good/important) #2: Always listen and learn but trust my own judgment and do what my instinct tells me!
