I am a marbling FAILURE!

I don't know how many times I've tried water marbling, but it just isn't happening for me. I am getting better and I'm learning what NOT to do but I haven't come up with anything I'd leave my house with lol.

I desperately want to do a rainbow marbling but apparently anything with a shimmer isn't going to happen. It either dries too fast or ends up looking like a big gunky glob on ugliness on my nails.

This was my first go at it tonight:

This was before I took the tape off and is a perfect example of WHY you should tape your finger up, it is M.E.S.S.Y!!!!!!!!!

The only finger that looked any good was my thumb, I used only cremes and it was PERFECT! So I went ahead and used that green and pink on my right hand. It turned out okay but it's not as nice and crisp as I want it to be. I want them all to look like my left thumb!

See this thumb? Isnt it pretty?

WHHHHHHY? Why can't I get the rest of them to look that good?

This is my right hand, it did turn out better than my right after I started using only the pink and lime creme polishes. Those are the only creme's I had that looked good together.

My middle finger turned out pretty good. Most of them have bubbles in them.

All I want is a pretty marbling mani, is that too much to ask?

Any pointers would be greatly appreciated!

Now I'm going to go take this mess off and get ready for my first Pink Wednesday :)
