I made the most beautiful quilt top I have ever seen from a serger. The book I used is Serge and Merge by Sharon V. Roth. I only wish I had used fusible thread in the lower looper. The upper looper thread shows and then you sew it down.
If I used the fusible thread All I would have had to do is press it down. Check it out on her website the "Mixed Bouquet" - I used one floral print and did the background red.
