Oh Katrine, that is just drop dead gorgeous!!! I can't wait to see it when it is all quilted...it is spectacular right now! I like your idea of FM blooms in the lilac blocks...you could stop with the stitch in the ditch on the pieced blocks..or you could add a small stipple on the outside of the pieced design and add a small stencil design inside the inner square....or you could add a small crosshatch...or you could just echo stitch around the outside of it... What are you doing in the sashing? Whatever you choose, it will be sooo pretty!
