Make a Waterproof Paper Mache Mushroom for the Garden

Today’s guest post is by Linda Bunnell, who made this life-like paper mache mushroom. She shows us how she made it and the product she used to make her mushroom weatherproof so it could stay outside.

I haven’t seen anyone using this product before, and I haven’t tested it myself, but it certainly opens up some exciting opportunities for experiments.

Thanks, Linda, for sharing this article with us!

How I Made My Waterproof Paper Mache Mushroom

Here are the steps by which I made my mushroom.


Some of the items I used to create my paper mache mushroom

I used:

  • 9 1/2″ plastic plate I bought at a thrift store, (you could also use a plastic bowl of the size you choose)
  • water bottle , (you could substitute a Pringles can ,etc)
  • plaster
  • plaster cloth
  • masking tape
  • newspapers
  • paper pulp
  • Rust-Oleum LeakSeal
  • Acrylic paint

Step 1:

Mix water & plaster & fill the bottle 1/3 – 1/2 full. Set aside to dry.

Step 2:

Wad up newspaper & tape to your plate until you get the desired shape of your mushroom cap , be sure to make a roll over the edge of the plate for the bottom edge of your cap.

Step 3:

Next cut a piece of cardboard to fit the inside of cap ( note black lines in photo). Find the center of your cardboard & cut a X to fit the plastic bottle & insert it cap first & tape & hot glue securely.

Cut cardboard as shown.

Step 4:

Cut strips of plaster cloth & wrap the bottle

Wrap stem with plaster cloth.

Step 5:

Cover your mushroom & stem with paper mache (strips or pulp). Let dry completely. This may take a while. Don’t forget to make your gills under the cap. (Note from Jonni – you could also use paper mache clay, or find a recipe for paper pulp here.)

Add paper mache strips of paper pulp to mushroom.

Step 6 (optional):

At this point you can coat your mushroom with a thin coat of Patch if you like a very smooth look. Let dry.

Use patching plaster to smooth surface.

Step 7:

After drying, spray with water sealer & let dry. You may coat it 2-3 times letting dry completely each time & making sure you get in all the cracks and crevices.

Step 8:

Now you are ready for painting. Use acrylic paint, a variation of near the same color , dark , medium & light. I chose Asphaltum brown, Raw Sienna & Buttermilk. I also used Antiquing gel & blending gel.

After painting spray a couple coats of a clear sealer.

Hope you have enjoyed this post. Please let me know how you did. Would love to hear from you.

Thanks , Linda
