i know what you mean. i did a mystery quilt once, and i experienced a level of anxiety the whole time. there were people who sewed faster than i did, and i avoided looking at them so i could experience my own first. i am not so sure i would do another mystery quilt with or without a group. it is just too anxiety-provoking and not worth it. heck...making a quilt where i know what the outcome is supposed to be is anxiety-provoking enough! best wishes in whatever you decide is best for you.
