Trio of Zentangle ATCs

I'll finish your Zentangle ATCs if you'll finish mine. LOL!!

Start with three blank 2.5" x 3.5" ATCs. Draw string on each one (preference: three different strings). Complete only one section of the string on each ATC with a Zentangle pattern (preference: a different pattern on each ATC). Send the three ATCs to your partner. Rate your partner upon receipt of the trio. Complete your partner's ATCs with Zentangle patterns of your choosing. Choose one -- the BEST one -- and send it back to your partner -- to be mailed no later than two weeks after receiving the trio. The other two are yours to keep or trade.
