|I just finished reading Marcy Tilton's book, "Easy Guide to Sewing Tops & T-Shirts." It contains three good tips for sewing knit tops that I thought the group would appreciate based on comments I've read in past pattern reviews.
1. Because the front of the body is larger than the back, Marcy recommends adding 1/2 inch to the length of the front pattern piece at the bustline. This 1/2 inch is then eased into the seam at the bustline when sewing. This gives a smoother fit to the front of the garment. (It may also eliminate the need for a full bust adjustment for some people.)
2. To prevent a garment from riding toward the back, she recommends balancing the armhole. For an armhole to be balanced, the back armhole must be 1/2 inch longer than the front armhole. If the front and back armholes are equal length (which is the case on many of the Kwik Sew patterns I've used), then she recommends adding 1/4 inch to the back shoulder seam, trimming away 1/4 inch from the front shoulder seam, and, if the pattern has a sleeve, moving the shoulder seam dot on the sleeve 1/2 inch toward the front. (This is essentially a forward shoulder adjustment.)
3. To prevent/minimize stretching and rippling, she recommends using a satin-stitch foot instead of a regular foot when sewing with double needles.
I am using the first two tips on a knit T-shirt I am making and am pleased with the results so far.
