Pins are for thick woven garments! A pin prick on something like a satin weave or into a knit might cause irreparable damage like runs or little holes. Oh no!
In fact, there are two different kinds of sewing machine needles for such particular fabrics- a sharp needle is for wovens where a ballpoint needle is for satins, knits and delicates. The sharp needle has a point which punctures the threads of a fabric; the ballpoint needle is blunt and finds the spaces between the threads of a fabric.
Pins include buttons, straight pins and safety pins- pictured above is a selection of vintage buttons available at the Sara Duke Factory Store on a vintage woven jean jacket. The shoppe is open on Saturdays 10 am to 6 pm, by chance or by appointment anytime- please contact firstname.lastname@example.org for more information.
