Yes, I am indeed making a G4 pack and this is my first experience sewing. It asks for three long bar tacks along the collar that sits overs the shoulder straps where they attach to the back piece.
I will probably just use the reverse stitch button held down to help alleviate the issues I'm having. I was hoping to not do that, because my Brother 6000i does reverse stitching VERY slow. The biggest concern is that I still have the issue of not being able to see the original stitch when reversing stitching which makes it difficult to ensure I am actually stitching over the original and not deviating to one side or the other of the original first stitch. I suppose if the presser foot was clear then I wouldn't really have any issues, but that's not the case unfortunately.
I suppose it will just take time and lots of practice on scrap material, which I was trying to do last night, but not having a whole lot of success.
