Here's a link to a Splendid Sampler finished quilt. The blocks are 6" sq.
https://bevanddara.com/2017/08/15/it...-still-sewing/ I think this would be an interesting setting for the SBS quilt also. This setting makes the blocks look like they are floating right off the quilt.
Here's another interesting setting as well. Say you didn't want to make all of the SBS Blocks. And, make an alternative block in between.....This setting could be fun too.
