Blue is my favorite color. The blues are the 7 background choices that are separate from the panel. Each block has one repeat blue in order to pair them with the stack-n-whack wedged pieces. If I liked yellow, that probably would have been a better choice.
I thought I made a tutorial, but couldn't find it.
These are pics from another project, which did not end up as a quilt because the background was tooooooo busy.

I'm not sure how big those are, but they would sure make fun trivets/hot pads/plant coasters... :-)

That is quite an eye catcher, very nice but I bet a lot of work.
