I'm not a professional and have only recently started working with latex. If there's any problems with it please feel free to contact me. :)
Start by taking your latex sheet or scrap piece and drawing a circle on it. I used a small tub as a guide.
Take your rotary cutter or scissors and cut it out. If you're using scissors make sure they're very sharp before using them. If they're blunt your circle will have jagged edges.
**Before using white spirit make sure you read the instructions on the back, it's very flammable and can be poisonous if consumed or inhaled**
In a very well ventilated room apply a small amount of white spirit to a cotton pad and clean the shiny surface of your circle. Cleaning it removes excess dirt and dust. This will help create a better bond when gluing.
After applying white spirit your latex will curl up, it will go back to normal shortly though.
Make a cut half way into your circle to the middle.
It should look a bit like this. Start applying a thin layer of latex milk to one edge. Once it has become tacky and almost clear create a cone shape by overlaying it.
Your pastie is complete! Now for the decorating!
**Remember the clean your strips before gluing**
Cut out as many strips as you want. I like to use my pastie as a guide so i don't cut too short.
Apply latex milk where necessary and wait for it to become tacky and almost clear.
Apply latex milk to your decoration then wait for it to become tacky and almost clear.
Don't rush this step like I did and forget to cover up the seam using the strips. :P
Apply pressure to your decoration to make sure it's stuck on properly.
Now your pasties are complete!
