For these, I just used one coat of nfu-oh Aqua Base (it takes quite a long time to dry!), and then applied one generous coat of holo.
So which one is which?
1. GOSH Holographic Hero (the new one)
2. FNUG Psychedelic
3. GOSH Holographic (original)
4. M&S Rainbow
I think the FNUG is a clear winner on this photo but in real life there is not much between that and GOSH original holographic. In certain lighting the new GOSH holo catches up with the other 2 aswell. Sadly M&S lacks in the holo department though. Don't get me wrong, it is pretty but the other 3 are just too good!
Which is your favourite?
