Before I start showing how to make this, let me just teach how to make a "tea/ content" for my bubble tea cups.
I have since decided that if I am going to make a "bubble tea" that I will remove the "bubbles" or boba just to be different.
Here are the bubble tea cups, straws and covers I made.
I am currently holding a resin colorant.
Pour a bit of a resin and then the color on a cup. Cure under a UV light and you'll have something like this.
With the cover on.
Done.
To make the character above. I started with this. Its just a standard bear form. I baked and have something like this.
Before proceeding with the resin part, make sure that your character fit inside your cat. It does not hurt to try inserting it first.
If the thing fits into your cup, start making you "tea"
Don't fill it. Make sure that you leave a "displacement" space for your character. If you're happy with how the character looks, cure it in the UV light and you'll have something that looks like this. Just add/ remove the straw. Its up to you.
