I absolutely fell in love with your charms! These are something I might want to try and do myself sometimes. I see you ink the lines of the pictures...is this necessary or could I use stuff like graphite instead? I also read somewhere than you need to rub the surface with a sandpaper first?
I don't ink it but most people do that: ink one side with a marker or something similar and color the other side, I use either graphite or colored pencils for the outline on the same side. You only have to rub the surface if you have the crystal clear type.
Thank you for such a quick reply I'd rather use a pencil for outlining myself as well. I don't really know what kind of shrink plastic the local stores sell but I'll have to try them out. But it's important that it's the transparent kind, right?
The original Shrinky Dinks comes from the USA, they can sell their own product in different countries though, I tried a type they sell in Hungary as well, but it wasn't that good (it was a bit ugly to color on it but it looked more transparent when baked ) so I started buying the plastic from the USA. If you are lucky you can find it too. The transparent is easy to use since you can sketch your picture on plain paper then just put the plastic on it and draw it over. I have the white type as well and the crystal clear, I haven't used them yet but I was just thinking about using the clear one to make fluorescent jellyfishes for my bathroom I suggest to buy the one that has been already scratched for it's sure that it made perfect for use. Bright white and crystal clear are not treated yet, I think they are better with markers used on them.
