My Giant Illuminated Mushrooms Brighten Up Every Place They Go

I knew I wanted to replicate the traditional mushroom

I started with the stem, using 2x4s, plywood and lag screws

Once upright, I stapled chicken wire all the way around to create a surface for cheesecloth

The caps were built so I could separate them from the stems for transportation

Using a 4x4, electrical conduit, pvc tubing and chicken wire, I got that mushroom shape just the way I wanted

I screwed the caps to the stems through their wooden bases and they were ready for their skin

The skin is a layer of cheesecloth or cotton scrim material that creates a surface for the foam

Using spray adhesive, I simply sprayed the chicken wire and attached the cheesecloth

Once everything was covered, I prepared for the spray foam

Spray Foam comes in a 2 part tank system. It is traditionally used for insulation but works wonderfully when building large props

It requires safety gear including a full body suit, respirator, gloves, and goggles

The foam cures quickly, rising up and hardening within minutes of application

I let the foam cure for 24 hours

Using a paint sprayer to get all the little nooks and crannies, I got painting

Using many gallons of paint, I sprayed and sprayed and sprayed

Creating the gills was a tedious and long process that involved pleating, pinning and hot glueing

Using 10 yards of 120" white spandex, I first pleated and stapled the fabric to the perimeter inside of the cap

Allowing for some drape in the fabric, I then pleated and pinned to the outside edge

I cut the excess fabric off

It was time to glue

I finished it off with hot glue and a couple skin burns along the way *ouch!*

I was quite happy with my build so I made many more and have been improving them along the way by adding Velcro, different paint colors, moss and lighting
