Oh, I remember now how it happened, I was too busy joking and laughing with my sister and niece as well as sewing and not paying attention to what I was doing the time and this was the result,but all was ok in the end when I undid the across one and sewed it right way up.
I think a lot of errors happen when we loose concentration or get interupted in what we are doing, but it's all good fun !! so long as no one dies what the heck !!!
