I undertook to make 40 little calico bags to put bath tea in. What bath tea is, I'm not absolutely sure, but calico bags I can do. It could be a trifle tedious to work on such small bags individually, so I spent some time working out a production line method. The dimensions of the bags were length 9 or 10 cm, width 5 or 6 cm. I drew a grid of blocks on my fabric of 22 cm by 8 cm and cut just the long side. I hemmed that on both edges:
I then cut the short sides to make rectangles. I folded them right sides together, with a piece of ribbon between the layers:
After sewing the right hand seam, I tucked the ribbon right in so that it wouldn't be caught by the left hand seam:
When I had a whole lot of these little parcels, I took them to a sunny spot for finishing off - snipping threads and clipping corners before turning them the right way round.
