This is our Free Poster Maker software from Wrapcandy.
You'll be able to open your digital image, make some easy edits and print out a poster on multiple sheets of paper.
Put them together and frame.. Simple and fun Poster project for the family.
There are a few nice tools that allow you to turn it grey scale but leave some elements in color. Like a hat, or a logo on a t-shirt.
All you really need, is your Windows Based PC and a printer to make nice posters.
This software is free, but does require a Free account to activate.
