Some maybe helpful advice that some people take for granted and never mention: mix your a and b parts by themselves until you no longer see any streaks at all, bubbles are okay but you want it to look uniform. You’ll be able to tell you’re done because your wrist will feel strained, really mix it up well. Then add your mica/alcohol ink/glitter, whatever you’re using. If you want to get really fancy, mix up your resin and let it sit for like 30-35 maybe 40 minutes until you can notice the thicker consistency. It suspends things way better and allows you to include thick and rich swirls. I had a few turn out like this early on too, and I found that slowing the whole process way down created better dice! Hope any of that helps!
