Introduction: Resin Geode Book Cover

Blue, the color of the sea, the sky,anything deep and mysterious. Now that resin is has a charming fearture of transparency, and I was also so inspired by the resin geode art piece by

- Mrs.Colorberry

- EvanAndKatelyn

So I combined the three elements together-blue, resin, geode, (and finally made it into a notebook cover) if you like anyone of them, be sure not to miss this instructable ;D


  • Epoxy Resin
  • Fragments of sea-glass(3 colors in total-transparent、light blue、dark-blue)
  • Silver foil(optional)
  • Silicone mold of a rectangle plate(you can also make one with foam board )
  • Notebook fittings-6 binder rings, filler paper


  • Resin mixing - electronic balance, cups, stick, resin pigment
  • Modification - tweezers, file/sand paper, heat gun


  • Mask
  • Gloves

Step 1: Prepping

Measure A with B and mix thouroughly.

【Notice】Remember to check the ratio! Mine is 3:1 yet others are 1:1, I put in 72g of A and 24g of B, this will come out as a 19cm*15cm*0.5cm plate. You can adjust the amout of resin according to your own mold.

Step 2: Creating a Geode!

From inside to outside, lay out three irregular rings of fragment sea-glass .

  • inner ring -dark blue (then add a little resin to it)
  • mid ring -light blue
  • outer ring -transparent (a bit more in quantity)

As long as it contains three gradient colors, it look just like a geode!

Step 3: Resin Filling

Separate the resin into three equal parts, add in blue pigment, turn their colors into transparent, light blue and dark blue. Pour them orderly from around the geode to the edge of the plate. Then mix the colors evenly.

Step 4: Decorating the Corner

Put in some more dark blue sea-glass in the corner as decoration, which also help improve the visual balance.

Step 5: Details and Modification

Now the things are done, would you like to add some details? For me I put a circle of tiny silver foil inside the geode, which come out not so obvious but still worth a try!

【TIPS】Then let the resin dry, don’t forget to cover it up to prevent the dusts!

Step 6: When It’s Dry It Looks Like…

THIS! Ohhhhhhh I love this blue~ what a fabulous and unique book cover.

Step 7: Back Cover

The back cove is made in the similar way of the cover, choose one single color (of the same scheme of the cover, here is blue) with less or even without any detail. As you see, I also drilled 6 holes to fit in the binder rings.

Step 8: Assembly

Now it’s time to put every pieces together! Everything I use fits to a A6 notebook, so make sure all your stuff fits to one another.

Step 9: Let’s Write Something…

What I made was a notebook, but you can also apply the element of “geode” to any other fields, from wall decoration, table to lamp, vase, or even soap or candles! The trick is simple-fragments& transparent, light color, dark color :) And thanks for watching!
