I'm making my first bargello too! I struggled for days with the order of my fabric. Still not sure I got it right, but it's all sewn together so I'm forging ahead. Love your fabric colors. I, too, would probably change the order of your fabric (but it's totally your choice). Bargellos typically are designed with the idea of a graduation of color values from one to the next. So, I would try going from the pinks to the purples to the blues and then see where you want that pop of color with the green, yellow and orange. If you want the striking contrast from one color the next, go with it. In the end, it will be beautiful either way and it has to be what you want. Hope you'll post your progress!
