A pitcher of margarita's helps wonderfully with the practicing :)
but seriously I am a doctor diagnosed perfectionist and I have just started FMQing and I freaked when the 1st,2nd and even the 3rd tries looked horrid. The instructor at the Quilt shop where I took the FMQing class said, "honey, you need a stiff drink, a margarita or wine cooler or something to relax you."
So hey I may turn out the be the best FMQing lush ever now...lol
