I am not very good at drawing on shrink film or drawing with permanent markers so I use digital designs I have already created. My digital designs are based on my own sketches and part of my work. Please do not copy my designs, create your own, it is much more fun! I have friends who make their Shrink Film pieces from their own hand drawings and do a lovely job with permanent markers and pencils.
It is important to know that they Shrink to about ¼ (or smaller) even though the instructions say they shrink to half. I think they mean half in all directions. Keep this in mind with your designs. See my main photo for an example of how much Shrink actually happens.
The shiny Shrink Film to draw on can be a challenge. I use a pencil (which erases well on the shiny stuff, but not on the matte or inkjet) to draw the outline then colouring pencils (just a cheap regular pack of pencils). As the piece shrinks the colour will intensify, so keep this in mind, especially when using the permanent markers.
If you are using the Inkjet film you need to plan out your page (in your chosen illustration software) so you can fit on as many pieces as possible to waste the least amount of film (but remember to leave at least enough room to comfortably cut them out). You then need to print it out onto the film (test on paper first). You should set your printer to average quality (not draft as the quality is too poor and not any type of photo quality, I used plain paper quality). The printer I used is a Canon. I have been told the Epson printers are unsuitable for Shrinkies (something about the ink). Also, don’t use a laser printer, your film will melt!
For the draw on Shrinkies I used off cuts of Shrink film from a workshop. For inkjet I used whole sheets. You can save your decent offcuts for making more things. Shrink film is great to play with and make little bits and pieces (more Instructables will be coming with details on how to make some other things with Shrink plastic).
