Step 1: Materials
*Old plastic bottles (esp 1 liter ones...they have a bigger surface for more butterflies, but any bottle with straight sides will do)
*Push pins (thumbtacks)
*A piece of wood that you are able to push the thumbtacks into
*Sandpaper (220 works best for me! :D)
*Polymer clay (browns and blacks mostly)
*Strong glue (I have used hot glue, but it doesn't seem to be strong enough. I suggest gorilla glue or some kind of epoxy)
*Sharp scissors or an exacto knife
You only sorta need:
*Clear spray varnish (preferably oil-based)
*Pearl Ex-which is a mica-based powder that makes the wings shimmer!
*Small black seed beads
*Gel acrylic medium (matte)
Step 2: Prepare the bottle
Cut around the top of the bottle to get the top off-all you want to use is the straight part of the bottle-no curves. Do the same to the bottom. As soon as you have a cylinder of plastic, cut down the side with the gluey goo to create a rectangle of plastic.
Now, you have to sand the plastic so that your paint will stick to it well. The side you will sand is the side that was on the outside of the bottle. I use 220 grit and sand in a circular motion until the bottle appears "frosted" or matte. You can also work to 400 grit, but I only use 220 because i want my bottle to be rougher, so that the paint sticks better.
