It's always interesting to see how any trend evolves. Patchwork, colour blocking, combining knits with wovens and creating sheerness with different guages.
Machine knitting allows the knitter to create see-through areas easily, mixing heavier yarns with very fine guages.
Handknitting is a different story. You can use a heavier guage yarn such as a chunky weight and use the same needle size for a fingering weight. This will lighten the yarn and provide some sheerness.
Another way is through stitch patterns called Drop Stitches, which can be used in a variety of ways. While knitting you wrap a stitch once, twice and even three times, letting the wraps go on the next row.
This stitch is especially effective and pretty with tape yarns.
