OK, I tried really hard to ignore the colorful squares, but they won.
I said to myself "just play with them a bit and try to lay out one quarter of the star".
And when that was done, "hmm, it would be a shame not to sew them togehter now".
Once the layout was ready, the sewing went surprisingly fast.
Sorry for the not very good picture from late last night.
I hope to start with the aqua-blue corner tonight.
