I print my stuff on photo paper BUT sometimes the ink runs when you put the glaze on it SO I glue the image on the cap and then put clear fingernail polish on it let it dry then put the glaze on it.
I do use things from catalogs...they work great and turn out cute.
I useSun and Moon Glaze. I found it on etsy and love it.
I do the interchangable necklaces and put the images on the inside so it doesnt poke your neck when wearing them.
Cant help with the bows
