Hi everyone~ I love black and white photos of my kids, so I am already thinking of my christmas cards. I want to take a close up of my two kids wearing santa hats with black and white film and then after its developed color in the hat red. I went and got a set of zig pens today and tried them out on another black and white photo, it never dried , but it also was made from one of those kodak picture makers, will that matter? why didnt it dry? is there another way to color in something other than the zig pens? thanks for any info. Dawn
