I made this bag back in August for a rainbow themed swap. It was tons of fun to make even if it did take a little longer than the swap requirements :)
Either side could be the front, but this is the side I picked for front:
Back:
Inside pocket, snap, and stitching detail (rainbow thread!):
And here are my planning and in-progress pictures and overly worded descriptions:
The plan, 12 color blocks with one each of ROYGBV (I cut out indigo, sorry ;) ) and one block to go between each with their common neighbor mixed in. Example is the block between Red and Yellow is Red, Yellow, and Orange.
Each block started as a 7" square but they shrunk throughout the process. Here they are on their own
Front side blocks:
Red / Red, Orange, Yellow / Yellow:
Purple, Red, Orange / Orange / Orange, Yellow, Green:
Back side blocks:
Yellow, Green, Blue / Blue / Blue, Purple, Red:
Green / Green, Blue, Purple / Purple:
And some more in-progress pictures
Starting to add the grey border:

Each side finished and ready for bottom and lining:
I love how the border makes each section "pop" instead of having them bleed together.
