stitching is life 
it’s a crude method that can be replaced with extensions, but at least it works.
a thing that could help you while stitching, is explode and endpoints.
- in the style panel, look for edges styles, and turn on endpoints, maybe with a 3-4 thickness. it’ll make all the endpoint appears bolder, makes it easier to stitch from point to point.
you can see here in a recent post, Dave uses endpoints to see where the lines end
- if you’re dealing with arcs / circles, the endpoints won’t show up. because all the lines are welded as one arc. if you want the endpoints to appear, you’ll have to right click on the arc and explode the curve. it won’t be an arc anymore, but then again, you’re about to stitch
