I use Iris pins ball head and silk for 80% of my needs, but one pin will not really do it all. And
this wrist cushion.
Let me point out, I have a need of several things simply because I work with clients as well. In my workroom, I tend not to use a lot of pins for construction. I use weights or trace the pattern to fabric to cut out pieces.
Draping, I tend to use #16 T pins, fork pins for plaids and cross seams and insect pins for really fine sheers. I also have the standard applique pins and a banker's box of regular dressmaker pins for jobs where I know I am going to ruin, bend or lose a lot of them.
The Bohin has a few issues...if I work with fine lace it catches on clients' dress, the band has never adjusted to my bony square wrist and unless I am using silk pins, they cushion is hard to get them into. However, for tailoring and male clients it gives a professional look. This is something far more important to the men then the women.
I really want to have one of the neck boxes like they have at Dior and Chanel. You can see it in the movie Signe Chanel, or the bad picture below.
In my workroom, I just use pins out of a box. A friend of my DH's makes me playing card boxes out of wood so all the specialized pins are in them, and I use the Iris out of the tin.
