Spray painting farm board with template

Hello, I'm currently trying to make a kids toy farm board, I've attached images of one I made with a brush and taped up, I don't like using tape because it peels the acrylic paint off. So I made a 3mm mdf template which I thought would work great, however the template may have been to light and lifted slightly leaving a very untidy paint edge. Does anyone have any good ideas on how I could achieve an efficient spray painting technique that leaves a good finish?

Thanks, David. tmp_25098-IMAG1001113290354.jpgtmp_25098-IMAG1000140033164.jpgtmp_25098-22 - 16_121617104005.jpg
