Have you tried the 10 minute quilt block from Suzanne McNeil. Oh my goodness what fun and so easy too.
This block is great when made from both charm squares or layer cakes. I have also made the quilt with an 8" blocks. Great for a scrap quilt or charity quilt. The skies the limit.
This technique is also the one I used on my last Mothers Day Tea a couple of weeks ago. As you will see from the photos any combination of fabric works well. I have included the demo at the bottom of this post from YouTube, enjoy!
