we really shouldn't sew over our pins. it's dangerous. if you don't wear glasses anyway, then you should put on some safety glasses to protect your eyes in the even a needle breaks and that little tip goes flying. and if you've ever had to dig a bent pin out of the feed dogs, you'd know what a pain that can be. every time it happens to me i get knots in my stomach because i won't know whether or not i've done damage to the machine until i get the pin out and try sewing again. so far i've been lucky. one of these days, though, my luck is bound to run out. :lol:
now that i've said "shouldn't", i'll confess that i have yet to learn my lesson. i still sew over them. sometimes i'm sensible and pull them out as the foot gets close. mostly i risk wreck and ruin by leaving them in. when the day finally comes that i have to write a big fat check to the repair shop, i promise i won't ask for pity. :lol:
