Hi Brandon,
Sounds like you created the line w/ the free hand tool (looks like a pencil) if this is the case then you need to go to the "outline" tool (it looks like a pen).
1) select your line
2) click on the outline tool
3) click on the pen that is on the fly-out bar
4) under the heading of "Line caps" select the line w/ flat ends
5) click "OK"
If this info was helpful to you, please let me know by clicking on the appropriate link below.
