I have completed it and will post a picture, but my ONLY issue is when I use acrylic to make "walls" and seal the sides, the acrylic gets pushed into the space where the water goes. SO I guess I'm going to have to use less acrylic and press softer.
Have you posted a pic? I am fascinated to see this cos I can't quite get my head around what it looks like or how you do it. Have honestly never heard of water nails before so would love to have a go. Please post a pic for us to see!
