When my mother taught me to sew more than 50 years ago (!), we always sewed over pins. But I have read repeatedly how bad this is for the timing of the machine if you hit one, so I don't do it anymore.

I sew over pins all the time when I use my Featherweight or mechanical Bernina, but now that I have a computerized Bernina I take great care to remove them.

I always remove, not too much of a pinner but when I do, do take them out.

I remove the pins before sewing over them and only sew over accidentally. I also find over the years I do less pinning.

I learned not to sew over pins when one pin shattered my needle - made me really glad that I wear glasses or I would have been off to the emergency room! I now pin backwards - the head of the pin is towards my left hand and the point of the pin is facing towards the edge of the fabric - and I keep the point of the pin more than 1/4 from the edge of the fabric, so I can fly right by those pins without risking another potential disaster.

I don't use pins anymore. I use Elmer's Washable School Glue. You can put on a dab at the intersection of the seams. If it is not correct, simply pull it apart and readjust. If it is good, then hit it with the iron. This helps it to hold better. Then sew away with no pins. Works great for binding too.

I sew over them all the time!

I use I think they are called 'silk pins' and if they are straight ie from left to right u can sew over them... They are finer than the normal glass head or quilters pins. I still get a weird feeling when the pin goes under the foot as if it's going to go bang ! Lol but it doesn't.

I have accidentally done it a few times, but try not to as my owner's manual says it can break the needle, and I do not want to hurt my machine.

Sorry going to be a bit of quilt police here, NEVER EVER SEW OVER PINS! When the vintage machines were built they were beautifully machined and manufactured and would sew through an iron sheet if you asked it nicely BUT with all the bells and whistles us quilters, and other sewers now expect in our modern machines you now have a far more delicate animal with swing arms, computer bits n pieces etc. etc. and they won't stand that sort of wear. Sew over a pin on a modern machine and you risk completing ruining the "timing", besides other things of the machine and however good your lovely service man is it will never be as you bought it ever again.

How do I know, I saw a member of my quilting class sew over a pin on a brand new £500 Singer machine, modern one, and she had to give it to her children to play with, good side of the story she picked up a lovely old Singer for £20 in a car boot sale and loves it to pieces.
