I do use the bias maker and try very hard not to have joins in an open area. If possible have the joins happen under a flower etc. I know it's not always possible but it is very difficult to camouflage a join even when doing the 1/2" bias when using the bias maker. IMHO
Trying to find a youtube which might demo it. Here's one with just the bias maker no seams.

This one she shows how to make long lengths of bias and the seam but doesn't show it going through the bias maker.
