IMO there is an art to pinning, and I chose to use a complete lesson, what is to me, the correct way to pin. This is of course just "my" way but it works. When piecing I pin frequently but at about 1/2" or a tad more from the edge, that way the newbies can concentrate on sewing and not worry about the pins as the presser foot will miss them, as they get a bit more practise they do as I do and remove the pins as they come to them or just ignore them
As far as bindings or something similar, like appliqué, I use the long flower head pins and put them in at right angles which makes them so easy to remove as you come to them,
A tip when a needle breaks and you can't find all the bits, turn your machine on it's side, unscrew and take off the bottom plate and with a torch explore all the parts underneath the bobbin workings, you will find a pair of tweezers will help get the pesky bit out. It's worth the effort as twice I have found it lodged in one of the gears!!!!!!!!!!!!!
