I can't believe I'm having trouble with drawing parallel lines of un- square objects such as for cutting flagstone. What tool do you use?
Here's a sample problem I had today:
None of the edges are square, so the square failed me.
Ace Hardware said they had no tool for drawing parallel lines. At Home Depot, I bought this "angle-ize" contraption - but it stinks like you can't believe (for a whole bunch of reasons).
PS: I ended up marking distance from the edge and drawing the lines connecting the dots ... but there MUST be a better way.
