This one was so easy! first grab your acrylic tumbler here : https://thestainlessdepotcompany.com/products/22oz-acrylic-tumbler-w-straw?_pos=3&_sid=9acaf24b5&_ss=r then you'll want to remove your lid, and sand your tumbler. Spray with water or alcohol to clean off the dust from sanding. I also used 1" painters tape, i got from Walmart, to tape off my top rim. Now your ready for glitter! mix up your epoxy, I only used about 1mL. Here is the epoxy I used for this project :https://www.alumilite.com/resins/amazing-clear-cast-plus/ once I applied my epoxy, and made sure there were no lines, I applied my glitter! the pretty pink I used for this project is Wednesday's by POG https://peachyoliveglitters.com/products/wednesdays?_pos=2&_sid=b99500b66&_ss=r Don't forget to remove your tape! set an alarm, for 20-30 mins before sealing your glitter and moving on to the next step you'll want to tape off your top rim again. Seal glitter with approx. 20mL of epoxy. remove tape after about 20-30 mins. then allow your tumbler to dry! adding bling to your lid!
