Picture frame or shadow box for pics and other accessories.?

I want to make a large collage? of pictures, and a few things that are like a quarter inch thick... I dont want one of those deep shadow boxes... so do they make thinner shadow boxes or do i use some kind of picture frame? Thanks|||I make shadow boxes and I make everything myself .Quarter inch is one of the size I use and I get good results .You can make them thinner.Take a picture frame and place it in the corner you are going to use and see how it looks .I take pictures and place them on the wail and then put the frame up step back and see how it may turn out .Good Luck .|||Go to Michaels or any craft store. I am sure they will have exactly what you are looking for.
