Last week， Margaret went to several different（3） （store） looking for special cards for her friends． Margaret likes all the friends equally． She wanted to find a card for each friend that was personal， and she wanted the cards to also look sort of（4） same． Margaret spent over an hour looking at cards， but she could not find the cards（5） were right．
Margaret had a great idea． She would make cards for each of her friends． But she wasn't sure how to make cards． She remembered （6） （hear）somewhere about Christmas Cards that（7） （make） by hand over a hundred years ago． She used the Internet to find out（8） （many） about these cards． She made notes for all the materials she would need and went back to the store to get them．
Margaret spent several hours working on the Christmas cards （9） （careful）． That night at dinner， Margaret showed her family the cards she had made for her friends． Even her brother thought they were great， and he almost never thinks Margaret's ideas are great． Margaret（10） （decide） to make each of her parents a Christmas card and one for her brother， too．
She always wanted to sail across the Pacific O ．
