Well I indeed got all those yellow triangles cut yesterday. Proud to report that I did indeed have enough of the corner squares, Pieces have been turned into sides which are being sewn now.
Looks like I'll make my goal with plenty of weekend to spare. Hope to get those fan blades cut, it's not as hot but it is more muggy this week and not so pleasant to work in the afternoon. We don't really have any plans for the weekend but something might come up to take me away from my sewing...
