I taught both of my sisters the basics of quilting and then set them out on their own (BTW, I am the younger sister, just for the record) :-) one sister once made a trip around the world as one of her first "on my own" quilt projects. When she showed it to me she asked why she had all of these extra squares. I debated if I should tell her those were not extra blocks, she had forgotten an entire row from top to bottom and from left to right in the quilt. I did tell her and we laughed and laughed.
have another sister who cranks out projects now like there is no tomorrow. matching seams, even rows, wave border - no bother to her, she wants it done and she wants it done now, matching seems be damned! I admire her courage to do what she wants and how she wants it.
I had many great people teach me throughout the years so I've decided there are NO BAD quilters and NO BAD quilts - there are only BAD quilt judges.
