I was confused too. I thought this was a single Irish Chain, but have only made one to date and it was a triple. Posted by

I called it a double due to the number of corners on the blocks, 12 (10 on SIC, 14 on TIC) as a quilter the 1st thing
I see is the block. As a piecer the 1st thing most see is the chain which is single on this quilt. That's why I used the word "theme" in the title.
That was my thinking on this top, and the wording of the title.
