I have a 3 thread serger & used it when I did garment sewing. I never used it to do seams, just to finish the edges of the seams. I would sew the seams on the sewing machine then finish/trim with the serger. I didn't think just the 3 threads would be strong enough for the critical seams. Didn't want to chance a 'split'.
