Today I was searching around the web trying to figure out how to set the line thickness in HTML5 Canvas.
I stumbled across this great cheatsheet:

It had the information I needed, after setting the context you do something like this to make the lines thicker:
1 | drawingContext.lineWidth=4; |
Then go ahead and do your stroke:
1 | drawingContext.stroke(); |
The line should now be more thick.
