Deep blue stands out nicely against the rest of the quilt in this version. However, another color will be just as lovely. Just make the contrasting hearts and inner border darker than the rest so the hearts predominate.
Beginning quilters will love how easy this quilt is to make, and experienced quilters will enjoy how quickly it goes together. You can speed construction even further by making 8 half-square triangles at a time (instructions are here).
The finished quilt, from designer Judith Sandstrom, is 40″ x 56″. You can easily add more blocks for a larger quilt.
