In addition to using twill, tabby or other types of weave structures, an easy way to add interest to your weaving is to use different colored weft yarns. Clasped weft is a technique that uses 2 different colored weft threads in the same row of weaving.
Working from the right pass the weft yarn through the open shed, creating a loop on the left side of the warp.
Thread the second yarn color through the loop.
With your right hand, pull the weft yarn back through the open shed, pulling the second yarn with it.
Place the yarns in the location that you want them to be, and straighten out the weft ends.
Beat the weft into place.
Note that this does create 2 rows of weft yarn in the same shed.
