The Love in a Mist quilt block is an easy block for beginners with only half square triangles, square in a square and square patches. This traditional style block was originally done with only a light and a dark or medium colored fabric. I had to do my own thing so I added in another color. Additionally, the center star could be a fourth color.
The Honeymoon quilt block is a fun star block to sew together and it is easier than you might think. With only half square triangles, hourglass units, and squares, it goes together quickly!
