Precautions for personal seal:
1. Appropriate size: the size of the seal should match the size of the work and be equal to the size of the inscription. It can be smaller, but it can't be bigger and indecent than the inscription. If the words are small and the paper is tight, you can use small joint beads to show consideration.
2, the number should be small: the number of seals, ancient and singular. There is a seal "use one without two, use three without four, and cover an odd number, which means supporting yang and suppressing yin." The number of prints should not be too much, too much will be messy and even usurp the host's role. If a work has several printing methods, it is necessary to choose different printing methods to avoid similarities.
3. Proper location: seal and be careful with the location. There is always truth, falsehood and density in a work. The secret place is not compact enough and can be filled with a seal; If the sparse place feels empty, it can be enriched by seals, just like moving a small "weight" to make the picture balanced and ironed.
