With so many similar tones in this version (browns, blues, greys), the color order has never been less important. Just make sure you're not using all the blues in a row, or all the darkest shades, etc. But for those of you who really like a plan, here's the order we used!
Caston A: Stone Blue (medium blue)
Caston B: Praline (brown)
Row 1: Pearl (lt grey)
Row 2: Dark Earth (brown)
Row 3: Fitzgerald's Sky (grey/aqua/gold variegated)
Row 4: Comfy Junkie (variegated greys)
Row 5: Azul Profundo (deep blue)
Row 6: Natural
Row 7: Polvoriento (neutral grey/brown)
Row 8: Black Forest
Row 9: Bobby Blue (aqua)
Row 10: Selection K (variegated purple/gold)
Row 11: Indigo (deep blue)
Row 12: Pearl Ten (dark greys)
Repeat this same order twice more, or, as we did, mix it up. Enjoy!
