Every now and then someone asks me how I get these straight stitches. On the pictures below you see the making of Leather Bag #11 and I zoomed in on the sewing machine I use. It is a Global LP 9971 C. For me it is important I have a fixed point I focus on to get straight stitches. I removed the standard protector next to the needle and replaced it with a paperclip that I shaped to function as a pointer. I point it to the outside of what I am sewing and determine the ideal distance to the needle. When I am sewing I keep my eye on the pointer and not on the needle. This works great for me.
