Transfers can easily be made using liquid polymers. The only two brands that I know of are Translucent Liquid Sculpey (TLS) and Donna Kato-Sauce. This transfer method produces a very thin and translucent “decal” that can be transferred to many different surfaces such as paper, polymer clay, wax, plastic, glass, or fabric. 

You will need:
a photo copied image (either black and white or color) from a toner based copier, a laser printed image, a magazine picture, colored pencil image, or an image made with heat-set inks, such as Ranger brand heat set inks. 

A foam brush 

A heat source such as an oven or heat tool (warning- TLS smells very bad while it cures but it is approved non-toxic however, be aware of the bad smell and work in a well ventilated area.)

A shallow container for ice water 

A piece of glass or clear heat tolerant/bake-able mylar. ***optional** This will give you a shiny finished surface

Chose your images and cut then out. I always cut my images about 1 inch larger than I want the finished piece to be. Not because it shrinks but because the edges are often quite fragile and sometimes tear.
Using a foam brush “paint” the liquid polymer onto your image. Spread it out thin and evenly be especially sure to get an even coat around the edges.
Bake or heat cure at manufacture’s directed temperatures. I usually use a heat tool unless I am making multiple transfers at once. To do this I hold the image still with long hemostats to keep my fingers from being burned in the process. If you are going to use glass or mylar, place the image, TLS side down onto the glass or mylar before exposing to heat. Check underside of glass/mylar to be sure that TLS is in full even contact all around or you image will have an uneven (part shiny, part dull) finished surface.
Once the TLS has been heat cured immediately plunge it into ice water and leave it to soak for at least 20 minutes.
After 20-30 minutes of soaking (longer is OK, you can’t hurt it) take image out of water and gently remove paper from image with your finger. Be especially careful around the edges they tend to be the most likely places to tear.
You can now apply your image to almost any surface with TLS (you must re-cure), white glue, or acrylic medium. I have even encased images in between layers of melted beeswax.

Additional ideas for liquid polymer transfers:
You can also transfer images to fabric by following steps 1 & 2, (be a bit more generous in your TLS coats), at step 3, place image TLS side down onto fabric and iron at medium setting, allow image to cool before peeling paper off of fabric. You may need to soak in water to remove all paper fibers from the transferred image.

I just learned of a new liquid polymer product called Liquid Fimo Gel and it can be ordered from Fimo-zone at the URL below.  I haven't tried it yet, I just ordered some and will be experimenting soon.  It may be easier to find than the others for those artists who are outside of the US.
