Okay, allow me to explain: aida cloth comes in various sizes. 14-count cloth requires 14 stitches to make an inch,
18-count requires 18 stitches to cover the same distance. Your picture is 320 by 224 pixels in size, which is
71680 regular stitches. That many stitches is gonna take at least 3 weeks of my time, not including hunting down all the various colors of floss and the aida fabric.
Some objects (such as the little viking) can also be outlined with back-stitching.
14-count cloth would be 23" by 16" in size, 18-count would be 18" by 12-1/2" in size. Also something for your consideration, how many different colors would you like the picture to have? Some colors can be created by blending different colors together on the needle.
You'll have to give some idea of how much the picture is worth to you.
