On one of the Tahoe sew evenings, I made a fresh new sample for Easy Does It, which uses 6 fat quarters. This is the Full Bloom collection by Bari J for Windham fabrics. You can't go wrong with polka dot for spacers. The spacers keep the fabrics from mushing together--the very reason I designed this pattern.
I should note that on this pattern, I like to choose an order for the 6 fabrics. With so few it is hard to lay them out randomly. If you look closely, you can see that the top row is 1234561234, the second row is 5612345612, and so on. Rows 123 are the same as 456. It is hard to tell, since they are jogged differently. The end result is a random look, but with a plan, to make it easy.
