How would you scale these? I'm not very good with image software.
Well, if you open them in paint and go to page setup yo can put in a percent in the Adjust to part at the bottom right of the dialouge box. as for scaling it to yourself, not really sure. What id suggest is find out how wide across your chest is, then multiply it by .8 then use that number to tell if you ned to scale it up or down. the default for this is ten inches across.
