I am not a perfectionist...that being said...I do like my work to be of high quality but I don't like ripping so unless it is a tragic mistake that is really visible I tend to ignore it ...or cover it up....another words quilt it out...one of the first quilts I made had a bad mistake right in the middle of the quilt....so I cut out a tulip appliqué and sewed it on right over the mistake....the best compliments I had on the quilt were that they liked the tulip....so make lemonade out of lemons if you possibly can....LOL
