Resin kind of moves around a bit in the molds as it's curing...so it really depends on what kind of glitter you are using. Chunky glitter wants to sink to the bottom & float on the back at the same time...so try using a toothpick to swirl it around...keep an eye on it for the first 1/2 hour to hour...then it should be fine.
Does that make sense?
Or ...you could do it in little layers...mix some resin & don't fill the mold all the way...add your glitter...let it cure...mix more resin...etc. This is my preferred method...you'll have more control.
Yep - thanks very much! I'm using really fine glitter and tried the layering method but I'll attempt swirling it around with a toothpick. I bought some chunky stars glitter confetti so I'll see how that turns out too
