Sewing a seam across the middle of a piece
This is hard to put into words, and it appears that is something that is rarely necessary when sewing a garment, but it does come into play when sewing a bag.
I am sewing a backpack. I am sewing a smaller curved compartment to the front of the main compartment, right sides together and this means that where this smaller compartment attaches to the main compartment that I cant just line up two seams like when you sew most seams. I have to draw a curved stitching line onto the main compartment. Then when I pin or baste it on to the main compartment I have to pin match very tediously all the way down the drawn seam line. I get the outcome I desire but it seems like there must be some trick to make it easier. Does anyone have experience with this? I’m sure they don’t have to pin match for an hour along the seam line before they sew this sort of seam in a factory. I hope I have described what I’m trying to do slightly clearer than mud.
