There is much information regarding modern quilts and what makes them different from the traditional quilt. Most quilters agree the primary feature that differentiates a modern quilt from a traditional quilt is that though there is a grid pattern, the overall pattern does not follow an overall set grid. There are other features that are consistent with modern quilts; examples are, bold geometric shapes that contrast with solid negative space.
What I enjoy in a modern quilt is the negative space. Minimal geometric shapes and lots of negative space in the modern quilt allows the stitch work to be seen. When using a contrasting thread the stitch pattern will pop. There are so many stitch patterns available today. I have the Bernina Q-Matic that produces high quality stitches that will add depth and value to a quilt.
