Changing colors at the beginning of a row or round actually requires you to change the color at the last stitch of the previous row or round.
The photos below demonstrate color changes using double crochet stitches. The example also illustrates changing colors between rows, but the very same principles apply to changing colors between rounds.
Step 1: When changing colors at the beginning of a row or round, you will actually need to change yarns with the last yarn over / draw through of the last stitch of the previous row or round. Pictured here is a yarn over with the new yarn.
TIP: When changing yarns, always leave about 4" of tail to weave in later. You can either lightly tie the tails into a knot, or just let them hang. When weaving in the ends during finishing, untie the knot (if made) before weaving in.
|Step 2: The new yarn is drawn through the loops on the hook and the previous row is complete.
