I took the fast way with 108 Classic. Arlenez, I have tried the diamonds but just can't get way to put them in groups and they are hard. I have a pattern for the 192 Tessellation. I sort the same pieces then put them together. I just can't find an easy way to do the diamond. I may try it with this puzzle because the colors will make it easier.
We are having a rainy day.
Wishing you all sunshine in your hearts.
