your half a star is BEAUTIFUL! you are doing a great job...and stop taking apart your quilt tops! when a top is finished...put it aside until you can get it quilted or tie it...but don't go un-do all of your piecing work. when you finally start getting them quilted and bound you will find that often quilting 'BREATHS LIFE INTO A QUILT' and what you 'thought' was not so good is actually very very good! they are not supposed to look (MANUFACTURED-PERFECT) they are supposed to look like beautiful hand created items!
