This is a pretty easy ornament to make though if you're new to cross-stitch, my best advice is to pay attention to the details. You really have to be precise and get the needle exactly through the holes or else the backstitching will be a nightmare; you know you've done a good job if the back of your stitching is nearly as neat as the front.
Then turn your soldier right side out; this was probably the most difficult part since he's small. (I found it easiest to press down from the top.) Then stuff him, turn in the bottom, and sew your toy solider closed! I was pretty nervous about sewing him together - had I cut the margins wide enough? were the sides even? - but in the end, my worries were for naught and I was pleased with how this one turned out.
