Sewing thread had less "give" or stretch than regular embroidery threads.

One reason to tightly stretch fabric with a hoop or whatever is to allow
for the tightness of the embroidery. If the fabric is very tightly
stretched, the embroidery will be OK when the fabric is relaxed.

Using layers of stuff that'll dissolve in water is also helpful. Waste
canvas helps keep stitching from being too tight without stretching the
fabric itself.

I can recall using layers of bathroom tissue to loosen seams for
decorative effects in machine-stitching. There are more efficient
methods, but I was inventing my own as I went along back then, never
mind how long ago. :-)
