What is economy quilt block?
Economy Quilt Block, also called “square-in-a-square” or “diamond-in-a-square,” is a traditional quilt block pattern that has become popular thanks to marketing by Red Pepper Quilts, Crazy Mom Quilts, and others.
It has a square in the middle that is surrounded by two sets of triangles. This makes for an interesting and useful pattern.
The size of the block can be changed to fit the pattern of the quilt.
