Have a Baby Lock Quilters Choice........the feed dogs are actually larger than any of the feet and the 1/4" mark goes right through them. Don't know about other machines...is this the standard? The 1/4" marking in the back is not visible as it sits right smack in the middle of the rear of any of my feet. And from the back of the throat plate to the edge of the rear machine bed there is less than a 1/4". My needle can only move to the left or right with no variations in between. If I use the 1/4" foot it only has one small hole which can only be used with the needle in the right hand position and since the machine defaults to the left when switched on I frequently forget and break my needles. Does anyone else have these problems and how did you solve it?
