Yes, you can print them in anyy size you want, even in black and white. I have a small picture of Thor’s Hammer in the back of my phone’s case, it works. You do need to keep them close to you (in your aura). You can use them 24/7, it’s best not to use too many fields at the same time. The fields are really like a set of instruction that you are downloading into your “program”. Downloading multiple file at the same time slow down the process, but once it’s downloaded it dosen’t matter. Also, if you didn’t already know the limit is subjective, you might have a naturally higher “tolerance” and that limits increase with time. I now use many more fields than I used to and they are still effective. The time needed to achieve permanent change also depend on the individual. You can think of it as a graduated line with relative numbers. If you think you are ugly of shy and have done so for a long time. It would represent a negative value, the fields need to bring the value up from the negative number to past a neutral state (zéro) untill you reach the final positive value wich represent the state that you wanted. If you are already somewhat confident you don’t necessarely need 6 month to reach it. I hope this analogy helps.
