Is it hard to hand sew a shirt?
Hand sewing a shirt is not as complex as it sounds, nor is it unnecessary in the face of sewing machine popularity. Shirts, particularly dress shirts, are often better if sewn by hand, as the technique increases the ease of the seams and provides more comfort than a machine-sewn shirt.
Can you make clothes without sewing machine?
In the absence of a sewing machine do a running stitch one way and then turn around and come back the other way covering all the gaps in between the previously sewed stitches. Assemble the shirt piece by piece, sewing them in the same way with the running stitches.
