The serging was done with multi-colored metallic thread in the upper looper and purple in the bottom looper. I used two strands of red yarn which gives it a red cast.
I have been finishing my small samples into pieces that I refer to as "Quilt Tiles". I've found that I appreciate them more and they are not lost in the confusion of stray bits that have no home and are always lost when I am searching for them. (Several quilt tiles hung together can make an eye-catching display.)
