How To Affix Objects On Correct Side of Snowman

I’m a beginner, and I suspect there is an easy answer to this question but it baffles me. I’m constructing a snowman, and his hat looks the same from all views. But his eyes, nose, mouth, and the buttons of his coat go on the front. But I can’t get these items to affix on the front. They all seem to want to go BEHIND him. Please help!
