How do I find sky islands?

[Cory the guy]

I'm making a sky bridge, but harpies are coming from all the directions, does that mean I'm close to something? I'm also really close to space and the gravity is low.

No, harpies will spawn anywhere, as long as it's high enough.

Also, the method of using a high altitute skybridge in order to find sky islands is only really effective on small (and maybe medium) worlds, but not on large ones. The difference in altitude where the sky islands are is simply too great on large worlds.

get the waterbolt spell book, soot it up in the air and is u hear it hit something that means there is a sky island above you:)

The quickest and easiest way to find floating islands is probably to use a Gravitation potion and just fly around, but aquiring one early on can be tricky.
Using Waterbolt or any gun (a Musket or Undertaker will do) with Meteor Bullets will also work - if you hear them hit something solid when you shoot straight up and/or see them coming back down, that means you hit a floating island. You can then just build up from the ground; using rope is a quick and easy way to build straight upwards.
