Joining two pieces of fabric together is deeply satisfying. In these photos I was creating one long piece of bias tape for the True Bias Calvin Wrap Dress. There is something about how the edges match-up and the straightness of the seam that gives me tingles much like ASMR (autonomous sensory meridian response) does for many folks. Seeing the final product of joining the fabric - the orderliness of the seam on the 'right' side - is the most satisfying aspect of the whole process.
P.S. There's a whole genre of ASMR sewing genre. Check it out! Google 'ASMR sewing'.
