I'd been obsessing about this since I made the square the other day. I'd remembered it incorrectly but I like mine as it is.
It's falling apart & faded from years of use but it's mine. I wrestled with myself in the antique shop for about 5 minutes before I folded it carefully & took it up to the cash register.
I imagine all these blocks are scraps from larger projects and now I plan to make my own.
