Here is the tutorial on how to Shrink Gears, Keys and Stamps. Now you can actually do whatever form and shape you want and also paint them with other type of materials like Ink, Acrylics, Markers, Embossing Powder, Stickles etc.
In this video I'm showing you the process on how to do do this, is very fun and is working for me beautifully. This is a good way to make your own charms and not spending so much money on metal charms. Now is obvious that the finish look with metal charms is outstanding and if you want to make your embellishments to standout having the real thing is the best way, but I like this alternative and I will save money down the road but I will use both ways for my creations.
I found out recently that Ranger has this paper called Shrink Plastic from the Inkssentials line and apparently is not easy to find, and Tim Holtz has a video about this. I used Shrinky Dinks and it works awesome.
