This block is known as Gothic Windows and was my hand work of choice for a few months during a very busy time when I needed some simple hand stitching in the evenings, as it requires little thinking. Just relax, cut, prepare, and stitch the curved heart sides using needleturn applique technique. After a few hundred you will become more efficient and faster! But you can decide to machine applique or needleturn by hand.
The sample is made with a wide selection of reproduction red and cream fabrics. Imagine it in colours that fit into a nursery for a new baby or raid your scrap baskets for the heart shape fabrics and combine with a neutral tone on tone print as the background. This is a great quilt to use as a two colour or even a scrappy version, just sort your main (dark) and light fabrics into two stacks. Make sure you choose a wide range of reds or blues or whatever your primary colour is as you need the variation of tone to make your quilt more interesting.
