Welcome to QB and to quilting! So sorry for your loss. For a newbie, GOSH your work is just lovely!! What you call 'mistakes' are really intended signatures for your unique work so not to worry. There are NO quilt inspectors here only friends. You keep on enjoying it because it does a whole world of good to be able to do something nice and to gain pleasure from doing so. With time the pain of your loss will ease. Take care and best wishes.
