To make the social icons you've added as image widgets to the right sidebar in the Comet theme, add this to your Appearance → Custom Design → CSS editor:
#c3 .widget_image {
background: none;
float: left;
padding: 8px;
}
#c3 .widget:first-child {
margin-top: 10px;
}
Note that this will adjust all image widgets in the right sidebar, if you want to add more image widgets later and you don't want the new ones to have collapsed spacing, then you can adjust the CSS to only affect specific image widgets. For now though, the CSS example above is quick and easy based on the content you've added so far.
