I agree that some pattern creators are just not all there! However that being said when it is somthing put together by a shop like on a shop hop - it is wise to look through it carefully immediately! these are not patterns that are being sold, and the person writing the instructions is not normally a pattern creator so quite often things are a little vague or left out. Ask me how I know- yep ran into the same problems you are having, turned out in the end with some creativity but now if I have to have one of those I check it out right away!
