The swapped squares were 5 inches. This quilter wanted a larger square, so added plain sashing
which made the square larger and emphasised the colour. Quite clever!
The more I look at this one the better I like it. The sash colour helps to define the rainbow stripes,
but because it's only on two sides the charm square isn't boxed in.
Instead of sashing the I Spy blocks with plain sashing, here the plain and prints are reversed. It's effective, isn't it. There are plenty more quilts on parade in the blog, lots of new ideas to try.
