I just found this great tutorial on image transfer – they cover lots of different transfer mediums for use on wood, paper, fabric, and glass. Xylene is a really toxic chemical, I’d stay away from it – the other mediums are pretty benign. I never knew you could use caulk!
An image transfer is, to put it simply, the act of transferring an image from one source to another. Depending upon what material you are wanting to transfer onto will depend on what type of transfer method you want to use. What I love about transfers as opposed to just taking the image itself and gluing it down, is the transparent effects you can get from transfers– allowing you to layer images or let the surface design show through. i.e. as a patterned fabric or woodgrain.
