I used 1/2" sequin pins for many years and am using them again, at least part of the time. Watch the video to see how this short pin compares to the 3/4" Clover pin and the 1" Shorter Perfect Pin.
The traditional head on this pin is easy to pick up and it gives you traction as you push the pin through the fabric. This pin is similar in thickness to the Clover 3/4" pin. Surprisingly, that thickness helps to keep the pins in the fabric as you sew.
