Zentangle Rainbow Series #6 INDIGO

Next rainbow swap is: INDIGO

Standard zentangle format: a sturdy 3 1/2" x 3 1/2" tile. Color is required (obviously), the predominant color must be indigo. Sender's choice, one partner one tangle. No other rules!

The series will follow the colors of the rainbow in order, so you can make ahead if you want: 1. Red (done) 2. Orange (done) 3. Yellow (done) 4. Green (done) 5. Blue (done) 6. INDIGO 7. Violet and 8. Roy G. Biv-- all the colors of the rainbow.

I'll angel but I hope that it will not be necessary.
