From Blue Mungo:
Tumbling Tones is a very dynamic quilt that utilizes the strip method to create all those Half Square Triangles. While the block layout and piecing method is the same, the three fabric options result in completely unique quilts.
TONAL (first photo) uses four different fabrics of the same color but in varying tones.
OMBRE (third photo) uses a jelly roll of ombre fabrics. It’s VERY important to note that each block requires two strips of the same color, so be careful when picking out a jelly roll for this option.
SINGLE (fourth photo) uses one fabric with a great amount of color or pattern variation to create a truly uniqe quilt.
