Akiva made a new tessellation out of pattern blocks. The limit to any pattern containing orange squares is always the orange squares. I tried to remedy this by purchasing some more pattern blocks. The new pattern blocks I purchased were off by ⅛” on both the blue and white diamonds, so I returned them and purchased some vintage pattern blocks on Ebay, which were fine. I wrote the pattern block company and sent them photographs of the measurement error, thinking they might be interested in a mathematical error in their math manipulatives. They sent me a new set of blocks, hoping that it was just a one-off on the size error. Sadly, it was not. Fortunately, the orange squares are all the correct size, so although I haven’t mixed in the new diamond shapes, we have more orange shapes than expected. Unfortunately, we still run out.

I have upgraded to the new version of my photo editing tool, ON1 Photo Raw. It has some really neat AI tools, most of which I won’t use. Here I have used the AI select tool to make the background completely black. So easy!
