Query: collage

I read glowing reviews of this book, so I bought it. I was disappointed, however, to find that the method requires special materials and tools. Nondeterred, I sought to track down the matte medium called for in the instructions, which turned out to be very difficult since I live in Japan and do not speak Japanese very well. After I triumphantly obtained the magic medium, I eagerly followed the guidelines for ironing the collage together, but found that my excellent and expensive Rowenta iron was not able to fuse the pieces together as demonstrated in Talbot's book. I ended up having to glue them, which is what I sought to avoid in the first place! To achieve optimum results, Talbot suggests using a special iron, which I am not about to buy, given my dubious results so far.
