Trying Resin in Paper Cups: A Beginner’s Experiment & Lessons

Resin art experiment using a paper cup with embedded flower petals and mica pigments in gold and blue, displayed on grass.

I can be a little impulsive when it comes to trying something new. But in this creative space I’m building, I like to think of it not as impulsive, but as curious and inventive.

I’m constantly asking myself:

  • What if I substitute this for that?

  • How can I get this look with the tools I have?

  • What if I just try?

This time, those questions led me to experiment with using party paper sanitary cups as a mold for an epoxy pour. I wanted to see if I could create something pretty and unique using just what I had at home.


Project Goal

My plan was simple:

Embed dried flower petals in the center of a resin pour, with layered colors of blue, rose gold, and mint green.

I wanted to see if I could get that effect using inexpensive party paper cups instead of silicone molds.


Materials Used


My Pouring Process

Here’s how I did it step by step:

Prepare the Resin

  • Mix equal parts of Dr. Crafty Crystal Clear Epoxy Resin thoroughly, following the 1:1 ratio.

Separate and Color

  • Divide the mixed resin into three containers.

  • Add mica powder (blue, rose gold, mint green) to each and mix well for a rich color.

Layer the Pour

  • Pour resin into the paper cup slowly, filling about halfway.

  • Place the dried flower petals in the center.

  • Pour the remaining resin over the petals to fill the cup.

Curing Time

  • Leave the cup to rest undisturbed for 24 hours to cure.


Results & What Happened

After 24 hours, I was excited to see the final piece.

But here’s the real result:

  • The party paper cup cracked clean down the middle.

  • The resin released easily, but the crack split the embedded flower petals into two perfect halves.

  • Instead of a solid, molded piece, I ended up with two separate halves of what I’d hoped would be one whole design.

Honestly, it was both disappointing and fascinating!


 Lessons Learned

  • Material Choice Matters
    Paper cups are too fragile to handle the heat generated as epoxy cures. They simply can’t hold up without splitting.
  • Proper Molds Are Essential
    Silicone molds are flexible and non-stick for a reason. Using cheap or improvised molds may work for small experiments, but for a clean, professional finish, it’s best to invest in the right tools.
  • Test Small First
    I learned the value of doing a tiny test pour with any new mold idea before committing to a full design.
  • Embrace Mistakes
    Honestly? Even though this didn’t work the way I hoped, I loved the process. It was another reminder to stay curious and not be afraid to try weird ideas.

Conclusion

Not every resin pour goes as planned — and that’s okay. I see every project as a chance to learn, even if the results aren’t perfect.

If you’re new to epoxy resin art or looking to experiment with molds, take it from me: start small, choose the right materials, and don’t be afraid to fail.
