So, to actually answer the question...I'm not afraid to fail nor am I afraid to try...except needle turn applique. I have never tried it and I just can't get myself to even attempt it because I think it would drive me crazy and who needs the aggravation?
I have taken several classes for needle turn. Each instructor has said my way is easy and you can be doing needle turn like a pro. I even took the backstitching needle turn class. I couldn't even do the basting part. LOL
I learned that needle turn applique is a skill I will not have so I did learn something.
