I took a stained glass class about 35 years ago. Spent tons of money purchasing the equipment. The teacher was so "perfect" I still don't like stained glass to this day. I see stained glass and the only thoughts that come to mind are how wrong I did it. Tell you sister to hang in there. Quilting is not about perfection, it's about how much we enjoy doing it. I try to quilt some every day and make some of the worst mistakes, but the good side is I am the "queen" of the seam ripper club. I am still proud of what I do-wobbly seams and all.
