I love working with contrasting warm or cool colors, sometimes in the same quilt, sometimes in two that go together. Like with "30 Degrees of Separation" I have the warm colors on one side and the cool on the other.
I've had it in my head that I wanted to do a similar theme, only in two co-ordinating quilts this time. So I chose an isosceles trapezoid shape (like a triangle with the top cut off, kinda thimble shaped) for both of them.
I used a variety of neutrals ranging from white on white to some dark tans and beige and everything in between.
One quilt has warm colors randomly mixed in: yellow, pink, orange, and red. The other has cool colors: blue, green, and purple. The quilts are both 18 x 22" with a one inch border all around each. They are both quilted with the same kind of background design, kind of a wavy pattern throughout, red quilting thread in the warm one, blue in the cool. They are aptly named: "Warm me up" and "Cool me down".
