i used adobe illustrator cs5 and created three ovals about 1.75 in and always had to keep each oval exactly the same size or the image wont come out proper, and i added specific images that really fit on to the piece, the real problem is trying to organize the images so that they dont overlap any other image, finnaly printed my object out on the Epilog laser wit thin acrylic, and used acrylic glue to hold the whole project together the glue is a pain, iit took several times to get it perfect, and use anything to hold it on the christmas tree anything works i used sring.
