Sorry I do not have a book reference, but there are three fantastic videos done by Nancy Zieman and Pam Mahshie (BabyLock) that may help her...
videos are great, will show her here with a cup of tea, and perhaps I need a searcher too ...
I really liked the series of books by Palmer and Pletsch. The first one is called Seing With Sergers and Book 2 is Creative Serging. By Pati Palmer, Gail Brown and Sue Green. Good luck. Make a rug, using all the square pieces of fleece you have. Helps to learn and you have a useful item at the end.
