How to free this sewing pin from the finished shirt I had something rather silly happen today. I altered the cuff of a storebought shirt, then machine washed the shirt. While hanging it, I noticed this: 



There is a pin left in the cuff. Its head is stuck between the two layers of the cuff piece, and its length pokes through the fabric. The shirt is made from plain, rather thin, cotton broadcloth. The offender is a glass-head pin, with a 2-3 mm head, and the head is larger than the stitch size I used to close the cuff. 



I don't want to: 


Open the nicely-turned-out, finally-finished, seam. 
Make holes in the fabric. 
Wear a shirt with a sharp pin poking at me. 


I am willing to sacrifice the pin itself, if that would help somehow.
Try crushing the glass head with a pair of pliers. If you're lucky, the metal head inside the glass is small enough to be removed without opening the seam.

If it's still stuck, cut the head of with wirecutters like Henry Taylor described. Keep in mind that the needle head may rust after being washed several times. You should tuck the left-over head into a corner that's as invisible as possible.
