I highly recommend everyone has a play with shrink paper once in their lives as it is THE BEST THING IN THE WORLD (although a little pricey). I use white A4 inkjet shrink paper as i usually print out Photoshopped designs, but you can also draw straight onto it and there's an alternative of frosted instead of white.
Before you begin bear in mind that your design will shrink by about 50% and the colours will become darker and more saturated as it shrinks. It will also shrink roughly 20% more on it's longer side (portrait way) so you will need to either stretch your design on Photoshop or draw one side elongated. It's a bit of a trial-and-error process.
What you will need:
- Computer (with photoshop)
- Cutting mat
- Chain (mine's a horrible yellowy gold at the moment)
- Jump rings
- Metal cutters
- 'Plastikote' clear sealer
- Shrink paper
- Hole punch
- Materials to create your deisign (paper, pens etc.)
- Oven gloves
Print out your design onto the shrink paper and cut out with a scalpel. The shrink peeps recommend you leave a white border around the edge but sod it, don't, cause it will look shit.
Punch two holes at the top of your design, aiming carefully to get close to the edge but not piercing through to it.
This is where the magic happens. Whack your design into the oven at 180° for 3 minutes.
HOW COOL IS THIS?? AHHHH
Ok so after all that excitement don't burn yourself, take your design out and leave to cool/harden. You may have to flatten it down with a spatula.
Once cooled, spray your plastic with a few layers of Plastikote clear sealant. This acts as a varnish to prevent any marks or dirt sticking to it.
After 20 minutes drying time, add jump rings to the holes. Measure your desired necklace length and cut chain accordingly. Add clasp and YOU'RE DONE!
