It all depends on the size of the pieces I'm sewing if I go without pins. I use the fine pins with the white head. I really didn't know there was much of a difference between fine and extra fine pins. I may have to buy some now.
Edited to add: I just googled extra fine pins and they have white heads on them, Dritz brand. They have glass heads on them. I wonder if that's what I have now? Hmmm
