I designed this pattern at age 15 with little to no graphic design experience. At the time, I was just getting to know my design program and didn't understand what screen printing and layers were. Yes, that means I drew it as a flat file. It took a ton of time to figure it out so, from that day on, I always use layers. Seems like a no-brainer now. Needless to say, I've come a long ways since then.
