I am passionate about making ambigrams from last 7 years, since I was
 in school. So i'm feeling really pleased to present you with my 
passion-art-project on AMBIGRAMS
Ambigram is a form of 
typography where you can read a same/ sometimes different word in two 
dimensions, usually when rotated through 180*.
Also known as:
Vertical Palindromes (1965), 
Designatures (1979), 
Inversions (1980) 
This art is a blend of Typography, Symmetry & Optical illusions
In
 spite of visiting online ambigram generators on the net, I was not 
satisfied because I failed to get all ambigram characters to allow us to
 easily create words on our own. 
So I decided to make it on my own.
Here I present the chart and the method to use it. 
DHAVAL’S AMBIGRAM FONT CHART
All
 the charectors in the above chart are designed by me & it took me 
around a month & a lot of hardwork to complete with it.
I
 know it’s not as perfect as it should be, but you can help to develop 
or replace the characters with better ones by mailing me your ideas on 
dhavalsartblog@gmail.com
*Create your own ambigram
1) Write a word (DHAVAL)
2) Write the same word in reverse order below the 1st word (LAVAHD) 
(You can also take the reverse of another word having same no. of alphabets)
3) Make Pairs 
(D-L, H-A, A-V, V-A, A-H, L-D)
4) Find the 1st part of the pair in the column & 2nd part in the row
 & note down the Character at the point of intersection (D-L) 
5) Do it with all pairs & note all the intersections in the order of pairs.
6) Your ambigram is ready.
Now you can customize & decorate your tattoo using your skills & creativity.
