Anyone have one? I have lost my manual, and Singer wants $15.00 for one: that really irks to pay that much for a paperbound manual. Anyhow, if you have one, can the needle position be shifted left, center, right? Mine is in left position, makes it difficult to get a good 1/4 seam. And can the feed dogs be dropped? More important, HOW? I bought this before I started quilting, and can't find any way to make these adjustments??
