Ever since my first shrinky dink experiment a few weeks ago – making bugs from recycled plastic – I’ve been wanting to try them again. This time I used “proper” shrink film, in both white and clear. I did some tests on the white film first to check out the optimum size.
I baked the test images in a preheated 300F oven. If you haven’t used shrinky dinks before then it is a great idea to run some tests first so that you get used to how they work. After a minute or two in the oven the shrinky dinks dramatically curl up, then slightly uncurl, making you panic that you’ll never get them flat. BUT – wait a little longer. If you’re patient then they will flatten out by themselves. If a shrinky dink curls up so much that it sticks to itself, you’ll need to use tongs or tweezers to carefully unstick it, before returning it to the oven.
Here are the before and after images and sizes for my test pictures:
Princess Crown 2.5 x 1.75″ shrunk down to 1 x .75″
Kitty 3.5 x 2.25″ shrunk down to 1.5 x 1″
Car 3.5 x 2″ shrunk down to 1.25 x .75″
Train 3.5 x 2.75″ shrunk down to 1.25 x 1″
Rainbow 2.75 x 1.25″ shrunk down to 1 x .5″
Football 2 x 3.5″ shrunk down to 1.25 x .75″
Based on my tests, here are some tips for preparing the images:
- Some images work better on white film (eg the football), and other images would have worked better on clear film (like the car and train)
- The colours get darker after baking; use lighter colours where possible
- If using jump rings to attach to the clip, only one hole punch is necessary
- Your zipper pull will look better if the hole is centred!
- Gaps in “colouring-in” WILL show after baking, especially when using white film
When the shrinky dinks had cooled, I used small pliers to attach a jump ring to the hole of each picture, and then added a zipper pull clip. I used lobster clasps (found in the jewellery making section of my craft store) for the zipper pull clip.
Here are some of my final designs!
They can be used on coats or bags – and would make perfect gifts, especially for mailing!
