Sandra, I think the repeated use of the sunflowers is going to give your project an extra design factor and it is a lovely choice. I'm especially big on fabric with meanings, especially one that can be shared with your sister like that.
I will say I was expecting some grid with the hourglass blocks and some neutral, but I was also thinking the garnet squares and maybe some of the aqua was coming in.
By my mental math, this step is pretty close in terms of neutral fabric use as that extra set I cut in the hourglass stage... I have plenty left for this step.
Hubby's official covid test on Jan 3 came out as positive again. He is expected back at work now on the 10th. I remain symptom free but because of test shortages am still not tested myself so we remain on the Keeping Isolated Sewing Solo (kiss) format.
