My Maternal Grandmother always said, "To be a good sewer, you Have to be a good ripper." Over the many years I have been sewing, this has been true, much to my dismay. I also believe that every "mistake" I make is a Learning experience to shift to that memory bank and remember not to do again.
We all have made many of the mistakes people talk about, and once we have we have learned from them...
Happy day & happy ripping.
