Quilt Size: 60" x 60". These 60 degree diamonds combine with simple triangles to create a striking Baby Blocks quilt. There are NO y-seams and the piecing is all done in vertical rows. There are a total of 84 diamonds to make this a great lap size quilt. Clear illustrations and full size templates are included, though it is strongly recommended that you use a multi-sized 60˚ ruler for cutting the triangles.
