I get 99% of clothes for myself and the boys at the thrift store. I love my thrift store. I have so many good things to say about thrift shopping that it deserves it's own post. Soon. But today we're talking about a sweater.
I tried it on at this point, to make sure the shoulder seams were in the right place. You want this seam serged before you sew up the side seam and underarm, so better to make sure it fits now. Once you're sure the seams fall nicely, go ahead and serge or zigzag stitch this seam.
Next you'll sew and then serge the side seams. Start at the hem and sew toward the armpit. Once to the point where the body meets the sleeve, line up your seams and sew on into the arm seam. Side seam and under arm seam are done in one long seam. Again you may want to try it on before you go back and serge this seam.
To finish your seams, thread all of your loose threads through a large eye needle and thread back through the first half inch of serging.
