Sometimes, but I use very thin, sharp "quilting" pins. They are much smaller in diameter than ordinary straight pins.

no, not any more -- Singer machine doesn't like them as they are the thicker ones

I've done it in the past, but just when I think I'm going good, I'll hit one and break the sewing machine needle. It's smarter to just pull them out as you get close to the needle.

I do and I know I'm not supposed to!!!

I try to remove them. I also try to pin over enough that the machine wont touch them.

I used to but since I have my electronic machine I'm afraid to.

Unless I'm matching seams I pin outside the seam line, paralell to it, and I don't have to pull them out. When I'm matching seams, I sew right up to the pin and then pull it out.

I always did, however when I was taking a class, the viking lady said no.. it throws your machine out of wack....
who knew..
so now I am trying not to...

I try not to but occasionally I forget and sew over one. My vintage sewing machines seem to be much more forgiving than than my computerized ones.

NEVER EXCEPT BY ACCIDENT AS MY HOME-EC TEACHER SAID THAT WAS A NO-NO MANY YEARS AGO
