Oh, those tiny metal objects that are so much under-appreciated! Yes, I am writing a blog post about the common safety pin. Aside from paperclips, I find it hard to think of a small object that is so versatile and yet so glossed over by many.
As a sewing hobbyist (I don't make money from it, so I'm reluctant to call myself a "seamstress"), I use my safety pins to pre-sew items. This helps me figure out complex instructions without wasting thread or damaging the fabric too much and helps in making sure the clothes fit the wearer correctly before I get too far with stitching. I also use the safety pin as a stitch remover in a pinch. The pointed tip is often sharper than my usual stitch remover, so it's easier to fit it under tighter stitches. I have used safety pins as emergency buttons (I bet you know many a mom or costumer who has done the same!) and as an emergency seam until I could get to a needle & thread. Last year my daughter used many safety pins to make wearable pins as part of Michael's Passport to Fun summer program. Do you remember making a pin "brooch" in school, perhaps for St. Patrick's Day or Mother's Day? I tend to use a safety pin or two to hold patches in place before I can sew them down. I also use safety pins to hold down the parts of clothes where a closure--button, hook & eye, zipper, etc.--will go in order to line everything up before I secure all the pieces. I even recently used a safety pin to fix my umbrella. One of the grommets that formed a joint fell out, so I slipped a safety pin into the holes and voila! a fully functioning umbrella once more. The main advantage of a safety pin over a straight pin, and thus the word "safety" in the name, is the fact that the sharp end is covered in the enclosure. I don't worry as much about folding up an in-progress sewing project with safety pins because no one will get pricked while moving it. And, unless I forget to close them, I'm not as worried about the damage that might be caused by a safety pin lying around.
I'm sure many people have used safety pins for many other things. These are just the few I remembered from more recent experiences. I would love to hear what others have done!
