Love the colors and the fabrics. Reminds me of Kaffe Fasset's colors, which I love.
Re the tape - I'm not sure what you mean by 'kept getting stuck to the other tape lines.' A.Did you tape ALL the lines at once? B.Or did it get stuck to the already-sewn lines?
Either can be remedied. A.Tape one direction at a time. B. Don't press the tape down hard on previously sewn lines.
If the tape is REALLY sticky, it helps to press it onto another piece of fabric first (maybe the back of something) to get rid of some of the stickiness) and THEN put it on your quilt to make your lines.
