Definitely a possibility! Think I did have an extra stitch, which may be due to a yo even though it wasn't called for. BUT can't remember if extra stitch came after many attempts to fix it or before. Hard to "undo" those attempts when I really don't know what I'm doing. Will keep your advice in mind for future use THANKS!
If it's true what that say ... you have to make mistakes in order to learn how to fix them ... I'll be an expert some day:aww:
