So here is a quick ( I DO Mean Quick!)of the construction of a polka dot retainer using the one-step method. Meaning you only have to cure this acrylic once. The results are not as crisp and pretty as the two step method, but this is quicker and there is less risk of shrinking the first acrylic color.
I sped this video up because I used it in my presentation, so it is just a quick view of the procedure. Now set to music! 😉
