How to make stained glass window nails

Start off with a clear nail tip (this is what will illuminate the polish)

Then cover it in splotches of your jelly polish (or regular polish mixed with top coat to make it see through)

I'll be using a stamper for my stained glass outline, but you can always freehand one with black polish

My freehand (way to messy for my liking)

After that just stamp (or freehand) the black on and add a topcoat 😊

When held up to light it resembles a stained glass window
